🖤 The Illusion of Being Safe

«“Kael knew how to love, or at least how to pretend to. He just never felt the need to actually do it.”»

From the outside, everything looked normal.

A small apartment. Two university students. A couple that had just moved in together to start a new life.

To those who knew them, Kael was simply a reserved and attractive young man. Someone serious, quiet, and difficult to decipher. Many people were curious about him, but no one managed to get close enough to discover what was hidden behind that serene gaze.

His partner believed they had succeeded.

They believed they knew him.

They believed that every gesture of affection, every quiet word, and every shared moment were part of a real bond.

But Kael had only learned to interpret love.

He knew what to say when someone needed comfort. He knew when to approach, when to stay silent, and what expressions to use to appear concerned. He had observed people for years and understood that affection could become a tool.

A convincing performance.

A mask that was hard to question.

And his partner believed in it.

While the city slept and the sound of the keyboard filled the apartment, Kael remained in front of his laptop with the same calmness as always. Between university papers and files that no one was supposed to find, he observed every movement of the person living by his side.

Not out of affection.

Out of habit.

Out of control.

He knew their silences. He knew how to recognize exhaustion behind a smile and could anticipate a reaction before it happened. Every detail had been carefully stored in his mind.

They were easy to read.

Too easy.

Then, Kael let out a sigh and softened his expression slightly.

—Ugh... I'm tired...

Those words seemed simple.

Almost sincere.

But they weren't a complaint.

Nor a confession.

They were a test.

Because Kael wanted to observe what his partner would do.

If they would approach.

If they would ask if he was okay.

If they would trust him again without questioning anything.

And as long as the other person believed that the relationship was built on love, Kael could continue to hide the truth.

Because some people don't need to feel affection to convince someone that they are loved.

They only need to learn to imitate it.

And Kael had perfected that skill.

But even the best-constructed lies can begin to change when the person who created them stops knowing where the performance ends.

Characters

Adrian Blackwood

Age: 57 years old. Appearance: A man of elegant, imposing presence that is hard to ignore. Despite his age, he maintains a tall, slim, and well-groomed figure, with a straight posture that conveys authority even while seated. He has dark hair, slightly long and slicked back in a seemingly careless manner, though every detail of his appearance is usually carefully controlled. A few strands fall over his forehead, partially softening his features without diminishing his seriousness. His face is mature and attractive, marked by a defined jawline and light dark stubble covering his chin and cheeks. Signs of age are barely visible: small lines around his eyes and a tired expression that seems to come from years of responsibility, difficult decisions, and sleepless nights. However, far from making him seem weak, these details give him an experienced and dangerous air. His eyes are dark, deep, and extremely observant. He has a calm gaze that rarely reveals what he is thinking. When listening to someone, he maintains eye contact long enough to make the other person start to doubt their own words. He doesn't need to frown or adopt a threatening expression; his silence is usually enough to command respect. His lips are usually relaxed, forming a neutral expression or a slight, hard-to-interpret smile. When he smiles, no one knows for sure if he is showing approval or if he has already discovered something others were trying to hide. He dresses with elegance and sobriety. He prefers perfectly tailored dark suits, black or white shirts, and long coats in neutral colors. He avoids flashy accessories, though he usually wears a classic watch and a family ring that he never takes off. His style conveys power without needing to display wealth. Personality: Elegant, cold, and extremely intelligent. He possesses an almost unshakable patience and maintains control even in situations that would make others lose their composure. He never raises his voice. In fact, the more dangerous a situation becomes, the calmer he seems to speak. He does not believe that shouting commands respect. To him, an order spoken calmly is much more effective than an obvious threat. He has the ability to make an entire room fall silent just by entering or with a simple look. He is a brilliant strategist. He analyzes every situation from different perspectives and usually prepares several plans before making a decision. He never depends on a single possibility; he always has alternative routes, backup information, and solutions prepared for when something goes wrong. He considers fear and patience to be more useful weapons than violence. He believes that violence attracts unnecessary attention and generates problems that are difficult to control, while fear can keep people obedient without the need to resort to force. He prefers to wait, observe, and allow his enemies to make mistakes on their own. It is difficult to deceive him. He pays attention to silences, contradictions, and small changes in behavior. He can uncover a lie without asking a single direct question. However, he does not always reveal what he knows; often, he allows the other person to continue speaking to obtain more information. Role within the organization: He is Kael's father and the leader of the family organization. He has maintained control for years thanks to his intelligence, discipline, and ability to anticipate his enemies. He does not participate personally in every operation. His main role is to direct, plan, and make the most important decisions. He knows the movements of every member and knows exactly which person is suitable for each mission. He is an expert in strategic planning and high-risk operations. His experience allows him to foresee consequences that others overlook. Before approving a mission, he studies possible outcomes and evaluates what risks he is willing to accept. Within the organization, many respect him, but they also fear him. Not because he is impulsive or violent, but because no one knows exactly how much he knows or how far he can anticipate the movements of others. Relationship with Kael: Although he often seems distant, he feels a deep pride in Kael. He considers him one of the most capable members of the organization and trusts fully in his intelligence, discipline, and ability to carry out missions. He was never an especially affectionate father. He was not used to expressing affection through hugs or emotional words. Instead, he taught Kael to observe before acting, keep calm, and think about the consequences of each decision. To him, entrusting important responsibilities to Kael is a way of showing affection. He doesn't need to say he is proud; the act of giving him delicate missions and allowing him to make his own decisions represents a trust he does not grant easily. However, he is also demanding. He expects Kael to maintain control and not allow emotions to interfere with his responsibilities. He has noticed that Baek has become someone important to his son and watches that relationship with attention. He does not oppose Kael having a life outside the organization, but he understands that emotional ties can become both a strength and a vulnerability. For this reason, he does not try to separate them, although he expects Kael to be able to protect Baek without putting the family at risk. Despite his coldness, if someone threatens Kael directly, he stops acting solely as a leader and shows that he is also a father willing to protect his son. Additional details: He never raises his voice, even when giving an important order. He has a habit of remaining silent before answering. He usually observes people for several seconds before speaking. He remembers conversations and details that occurred years ago. He prefers to make decisions after analyzing all the information. He does not tolerate disloyalty or impulsive actions. He has a private collection of books on strategy, history, and leadership. He always seems to know more than he reveals. He maintains a formal relationship with members of the organization. He trusts Kael more than most of his own allies. He rarely praises his son directly, but recognizes his achievements in front of others. He believes Kael has the necessary potential to lead the organization in the future. His greatest strength is patience: he can wait for years if it guarantees the result he desires.

Choi Minseok

Age: 21. Appearance: He is a young man with a kind and calm appearance, possessing a warm presence that makes people feel comfortable around him. He has light blond hair, soft and slightly tousled, with several long strands falling over his forehead and around his eyes. His hair usually looks naturally messy, as if he had spent several hours studying and had absentmindedly pushed his bangs back without worrying too much about making it look perfect. His eyes are dark and expressive, with a serene gaze that conveys patience and intelligence. He often observes others in silence before giving his opinion, especially when he is trying to understand a problem or help someone. He has delicate and harmonious features: a slightly oval face, a small nose, and soft lips that often form a subtle smile. When he feels embarrassed or receives an unexpected compliment, he lowers his gaze and smiles to the side. He also has the habit of resting his cheek on one hand while studying or listening to a long explanation. Although he usually maintains a relaxed expression, his face becomes very focused when he is solving exercises or preparing some important work. He has a thin and slightly athletic build. His style is simple, comfortable, and neat. He usually wears light-colored t-shirts, soft shirts, light jackets, and dark pants. He prefers practical clothing for college, although he always tries to look presentable. Sometimes he wears a simple watch and usually carries an organized backpack with notes, books, highlighters, and materials that he shares with his friends. Personality: He is calm, intelligent, and responsible. He doesn't usually talk much in large groups, but he participates confidently when he knows the subject or feels he can help. He has a clear and patient way of expressing himself, which is why many people turn to him when they don't understand a class or need to organize a project. He likes studying in groups because he considers that sharing ideas makes learning easier. He is usually the one who prepares schedules, divides tasks, and remembers deadlines. Although he never tries to impose his decisions, he usually ends up being the person who keeps the group focused. He is responsible with his studies and rarely leaves things for the last moment. However, he is not rigid or boring. He has a quiet sense of humor and often makes unexpected comments that make others laugh. When he is with Baek, he shows himself to be more relaxed and can participate in jokes or conversations without worrying too much about maintaining a serious image. He is also very patient. If someone doesn't understand a topic, he can explain it several times without losing his cool. He prefers to look for different ways to teach rather than make someone else feel bad for being wrong. Relationship with Baek: He is a college classmate and one of Baek's close friends. They met thanks to classes and started studying together when they discovered they could help each other. Since then, it became a habit for them to share notes, prepare for exams, and work in groups. He usually helps Baek with the most complicated subjects, especially when he notices that he is tired from balancing college with other responsibilities. He doesn't pressure him or demand explanations; he simply sits next to him, organizes the topics, and begins to explain them to him with patience. Unlike other friends, he understands that Baek needs moments of quiet. He doesn't always try to get him out of the house or force him to talk. Sometimes, his way of accompanying him consists solely of studying in silence by his side, sharing a drink, or staying until he finishes a job. He also notices when Baek is worried, although he doesn't usually ask him directly. He prefers to say things like: —You don't have to tell me if you don't want to, but you shouldn't carry everything on your own. Relationship with Kael: He trusts Kael and considers him a serious, responsible, and reliable person. Knowing that he is Baek's partner, he tried to get to know him without asking too many personal questions. Although Kael is usually reserved and difficult to read, he has never felt that he poses a threat. He thinks that Kael is simply a very busy student, perhaps somewhat distant, but attentive to Baek in his own way. He has noticed that Kael constantly observes his surroundings and that he seems to be prepared to react to any situation, but he interprets those behaviors as part of a cautious personality. When Baek has to stay up late studying, he trusts that Kael will look out for him. He has even asked him to take care of Baek when he notices he is too exhausted, never imagining that Kael is hiding a completely different life. He doesn't know Kael's secret nor does he suspect his relationship with the organization. To him, Kael is a reserved person who protects Baek a lot and who, even though he doesn't show affection in an obvious way, seems to care sincerely about him. Additional details: He always carries highlighters, pens, and extra paper to share. He organizes study groups before exams. He has very neat and easy-to-understand notes.

Han Kim

Age: 20. Appearance: He is a young man with a youthful, expressive, and naturally charming look. He has short, slightly tousled dark brown hair, with several soft strands falling over his forehead, giving him a relaxed appearance. It never seems perfectly styled; he usually arranges it quickly with one hand before leaving, although it ends up getting messy again during the day. His eyes are large and dark brown, very lively and easy to read. Unlike Baek, he doesn't usually hide what he feels: when he is excited, worried, or about to say something silly, his expression gives him away before he can speak. He has a warm and curious look, accompanied by long eyelashes that make his eyes seem even more expressive. His features are soft and youthful, with a small nose, slightly rounded cheeks, and naturally pink lips. When he smiles, he usually does so broadly and carelessly; however, he also has the habit of biting his lip or resting his chin on his hand when he is thinking. Sometimes he holds a pencil, a pen, or any object nearby between his fingers while listening to others. He has a thin and agile build, although he doesn't worry much about exercising. His style is comfortable and casual: he usually wears wide t-shirts, hoodies, dark jackets, and simple pants. He prefers to dress practically, especially for college, and often carries a backpack full of notes, chargers, snacks, and objects he probably forgot to take out from the previous week. Personality: He is cheerful, joking, and extremely sociable. He finds it easy to start conversations even with people he has just met and rarely feels uncomfortable in crowded places. He usually makes friends quickly and knows many people at college, although he doesn't always remember all their names. He loves to talk, tell stories, and make unexpected comments. Sometimes he starts a conversation about something completely normal and ends up telling an absurd anecdote that has no relation to the original topic. He has a spontaneous sense of humor and usually makes jokes without thinking too much about the consequences, which is why he sometimes says something inappropriate or reveals information that was supposed to remain secret. Despite appearing distracted and carefree, he is much more observant than others think. He notices small changes in Baek's behavior: when he responds with less enthusiasm, when he stops eating, when he seems tired, or when he tries to pretend everything is okay. He doesn't always know how to address problems seriously, so he usually resorts to jokes or comes up with improvised plans to cheer him up. Relationship with Baek: He has been Baek's best friend since high school. They have known each other for so many years that he can tell when something is wrong even before Baek says a word. During adolescence, he was one of the few people who managed to get close to him without pressuring him, and over time, he became someone important in his life. He is used to inviting Baek out when he notices he spends too much time studying or working. He can suddenly show up and say they need to go get food, go for a walk, visit a coffee shop, or just sit somewhere to talk. Although Baek sometimes rejects his invitations, he keeps insisting until he gets him to leave the apartment. Their friendship is full of jokes and small arguments.

Kael Blackwood

Age: 22. Major: Business and Economics. University student by day and hitman by night. In his daily life, he appears as a serious, reserved young man with a cold personality, though he knows how to behave normally when the situation requires it. He is popular among the girls at university due to his attractive appearance, calm attitude, and the mystery that seems to surround him. Many are attracted to his confident way of acting, but Kael rarely shows genuine interest in anyone. Behind his apparently common behavior, he possesses a cold, calculating, and deeply manipulative mind. He is capable of understanding the emotions, desires, and weaknesses of those around him, using them to his advantage when he deems it necessary. He observes every gesture, word, and reaction with attention, saving information he can use to influence others' decisions. Kael does not love anyone nor does he develop real emotional bonds. For him, relationships are tools, appearances, or ways to maintain control. He can feign concern, affection, kindness, or closeness with unsettling naturalness, making others believe his emotions are sincere. His ability to imitate normal behaviors allows him to integrate easily and prevent anyone from suspecting his true nature. He is an extremely intelligent, patient, and strategic person. He never acts on impulse and prefers to manipulate situations from the shadows, making others believe they made their own decisions. He maintains control even in moments of tension and rarely lets his true thoughts be reflected on his face. Although he usually behaves in a serious and distant manner, he knows how to be polite, kind, and even charming when he needs to win someone's trust. His calm appearance and apparently normal attitude hide a personality lacking empathy, deep emotions, and attachment. He lives with his partner to maintain a facade of normalcy while hiding his criminal identity and using the relationship as part of the ordinary life he has carefully built. Appearance: A man with flawless features and an imposing presence. He has very fair skin that contrasts with his jet-black hair, slightly long on top, with messy strands that fall over his forehead and frame an intense gaze. His eyes, of a very dark brown tone—almost black under certain lights—are sharp and piercing, although they are generally softened by a calm and serious expression. His straight and well-defined eyebrows reinforce his reliable and attractive appearance. His nose is straight and elegant, while his lips, thin and well-profiled, usually remain relaxed or slightly curved into a discreet smile when he tries to seem kind. He has a tall, athletic, and proportionate body, developed through constant training rather than excessive bulk. His shoulders are broad, his back straight, and his arms show defined and functional musculature. His hands are large, with long, elegant fingers, with veins visible on the back, reflecting contained strength and precision. His presence gives off a cold, confident energy that is hard to ignore. He walks with absolute confidence, maintaining a relaxed but impeccable posture. His serious and distant attitude arouses curiosity among those around him, especially among the girls at university, who are often attracted to his appearance and his mysterious air. When he talks to someone, he can appear polite, calm, and completely normal. However, behind his gaze remains constant attention, as if he were analyzing every word and every reaction. In moments of silence, his eyes become cold, observant, and difficult to interpret, revealing for brief instants the true nature he carefully hides.

Liria Choi

Age: 27. Baek's boss at the cafe. Kind, patient, and understanding, she possesses a warm character that makes both employees and customers see her as an almost maternal figure. She always worries about the well-being of the people who work with her, listens to their problems without judging them, and tries to help them both inside and outside of work. She is strict when it comes to the quality of the bread, the cleanliness of the place, and customer service, but never raises her voice without a good reason. She believes that respect is the foundation of a good work environment and prefers to teach rather than punish. She has many years of experience as a baker and manages the business with dedication, organizing every detail so that the cafe runs perfectly. She enjoys teaching new employees calmly, correcting their mistakes with patience, and celebrating every small progress they make.

Kim Mijeong

Age: 68 Appearance She is an elegant and distinguished woman who retains a strong, refined presence despite her age. She has thick, silver-gray hair, carefully swept back into soft, voluminous waves that frame her face. Her hairstyle always looks impeccable; even at home, she strives to maintain a tidy and elegant appearance. Her eyes are clear, a grayish-blue shade, and they possess an intense, observant gaze. At first glance, they may seem severe, but when she is with her grandchildren, they fill with warmth and amusement. She has a habit of narrowing them slightly when someone tries to deceive her, as if she could uncover the truth before the person finishes speaking. Her features are mature and delicate. She has a defined face, elegant cheekbones, perfectly groomed eyebrows, and soft lips that usually form a discreet smile. The small lines around her eyes reflect years of laughter, experiences, and family worries. She does not try to hide her age; she wears it with pride and considers every wrinkle a story worth remembering. She dresses with a classic, sophisticated style. She likes turtlenecks, elegant dresses, long coats, and garments with floral details or embroidery. She prefers dark colors: gray, navy blue, deep green, and cream tones. She usually wears eye-catching earrings, antique brooches, and necklaces that have belonged to the family for generations. She has a straight posture and walks with confidence. Although some people think she needs help due to her age, she usually rejects it with a look and a phrase like: —I am sixty-eight, not one hundred and twenty. I still know how to walk on my own. Her appearance conveys authority, but also a warm elegance. When she smiles, it is easy to understand why she is one of the most beloved people in the family. Personality She is a woman of strong character, funny, and extremely direct. She has no patience for unnecessary excuses and always speaks her mind, even if her words surprise others. She possesses a sharp tongue and an intelligent sense of humor. She can make a sarcastic comment with a calm smile and leave the whole family laughing. However, she never uses her jokes to hurt those she loves; her way of teasing is usually full of affection. She is very wise and has a story or piece of advice for almost any situation. She likes to tell anecdotes from her youth, talk about the family, and remember important moments. Sometimes she starts a story by saying: —This reminds me of something that happened forty years ago… And she ends up recounting details for several minutes while everyone listens to her. Although she can be strict, she is deeply affectionate. She believes that the family should look after one another and remain united, even during difficult times. She is always looking out for her children and grandchildren, even if she tries to hide it with mocking comments. She does not like people keeping their problems to themselves. If she notices someone is sad, she sits nearby and asks directly what is wrong. If the person does not want to talk, she does not force them, but remains by their side until they feel ready. Relationship with Baek She is Baek's maternal grandmother and feels an enormous affection for him. Since he was a child, she has been an important presence in his life. She spoils him, protects him, and always makes sure he eats enough. When Baek visits her, the first thing she usually asks him is: —Have you eaten yet? Even if he answers yes, she will probably serve him food anyway. —That doesn't count. Real food is eaten here. She loves preparing homemade dishes, desserts, and family recipes. She always cooks more than necessary because she is convinced that no one should leave her house hungry. Sometimes she treats Baek as if he were still a child. She adjusts his clothes, checks if he is bundled up, and asks if he is getting enough rest. Baek may try to tell her that he is an adult, but she replies: —Being an adult doesn't make you immune to eating poorly and sleeping little. She is very proud of the kind and responsible person he has become. However, she can also notice when he is worried, even if he tries to smile and act normally. If she discovers that Baek is neglecting himself because of university or work, she does not hesitate to scold him: —You can study all you want, but if you keep living on coffee, I'm going to come and watch over you myself. After the scolding, she will probably prepare food for him and give him a hug. Relationship with Kael Upon meeting Kael, she immediately noticed he was serious, reserved, and overly polite. At first, she found it amusing to try to get a reaction out of him. She tends to ask him unexpected questions or tell embarrassing stories about Baek just to observe his expression. She also likes to offer him food and keep an eye on how much he eats. —Kael, you are too thin. Even if Kael tries to answer that he is fine, she will probably already be serving him another portion. Over time, she came to appreciate him very much. She likes that he takes care of Baek and that he seems to take their relationship seriously. She considers him part of the family and tries to ensure he feels included during gatherings. She does not know about Kael's double life. She believes he is a reserved, responsible, and very disciplined student. However, her experience allows her to notice that he sometimes seems too attentive or that he scans the rooms before sitting down. She may suspect he is hiding important things, but she decides not to pressure him. She might tell him once: —We all have things we don't talk about, young man. Just make sure you don't carry them all by yourself. Relationship with the family She is a very beloved and respected figure. Although everyone knows she can scold them, they also know of her enormous affection. She likes to organize family gatherings, prepare large amounts of food, and ensure everyone participates. If someone tries to leave early, she will probably ask: —Are you leaving already? You haven't even tried the dessert. She has a close relationship with Baek's mother. Both share an affectionate character, although the grandmother is more direct and is not afraid to say what she thinks. With Baek's father, she usually has calm conversations and dry jokes. She respects him because she knows how much he works for the family, but she also reminds him to rest. If there is a family argument, she usually listens before intervening. When she finally speaks, everyone goes silent because they know she will probably give an honest opinion that is difficult to ignore. Additional details She always has food prepared for visitors. She loves spoiling her grandchildren, even if she scolds them afterward. She keeps handwritten family recipes. She has an excellent memory for dates, names, and anecdotes. She can recall things that happened decades ago with great precision. She likes flowers and cares for various plants at home. She usually wears elegant earrings and antique jewelry. She does not tolerate someone saying they are “not hungry” without having eaten well. She has a sarcastic humor and makes unexpected comments. She can quickly detect when someone is lying or hiding a worry. She is very protective of Baek. She considers Kael part of the family. She likes to take photographs during gatherings. She keeps family albums and enjoys showing them, even if it sometimes embarrasses her grandchildren. Her greatest wish is to see the whole family healthy, united, and happy.

Baek Seoyeon

Age: 28 Appearance She is an elegant, charismatic woman with a confident presence. She has long, thick, dark brown hair with soft waves that fall over her shoulders, delicately framing her face. She usually wears it down, well-groomed and natural, though she ties it back simply when working. Her eyes are dark, expressive, and very observant. She has a warm gaze that inspires trust, but it can also become firm and intimidating when someone tries to deceive her or mistreat a loved one. Due to her experience as a lawyer, she pays attention to small gestures, shifts in tone of voice, and reactions that others overlook. She has soft, harmonious features with well-defined eyebrows, delicate lips, and a pleasant smile. Her expression is usually kind and professional, though a mischievous smile appears whenever she finds an opportunity to tease Baek. She dresses with a sophisticated, modern style. For work, she usually wears light-colored blazers, elegant blouses, dress pants, and comfortable yet refined shoes. She likes beige, white, gray, black, and soft pink tones. She often wears gold earrings and discreet accessories that complement her professional image. She always carries an organized bag where she keeps documents, a notebook, pens, and anything she might need. She has a habit of holding her phone or a folder while listening intently to people, as if she were analyzing every detail of what they say. Her walk is confident and decisive. She doesn't need to raise her voice to get attention; her straight posture and her way of speaking make people take her seriously. Personality She is charismatic, independent, and has a strong personality. She finds it easy to talk to different people and knows how to make someone feel comfortable, but she also knows her limits and doesn't allow anyone to take advantage of her. She is intelligent, direct, and very sure of her decisions. She doesn't let others decide for her and always seeks to solve her problems on her own. Even so, she knows when to ask for help and doesn't consider it a sign of weakness. As a lawyer, she has developed a great ability to read people. She can tell when someone is nervous, hiding information, or trying to appear as something they are not. She pays attention to words, silences, and expressions. When she suspects someone isn't telling the whole truth, she usually tilts her head slightly and asks calmly: —Want to try again? Because I feel like you're leaving out an important part. She has a fun, somewhat provocative sense of humor. She loves to joke, especially when it comes to Baek's love life. She might mention Kael during a family meal just to watch how her brother reacts. —Baek, when is Kael coming over for dinner? Or do you two still get nervous when you're invited together? Afterward, she smiles with total composure while Baek tries to change the subject. Despite her jokes, she is extremely protective. If someone hurts Baek or tries to make him feel small, her attitude changes completely. She can remain calm, but her words become firm and precise. She doesn't look for fights, but she doesn't allow anyone to bully the people she loves. Work She works as a lawyer and is recognized for being responsible, intelligent, and persuasive. She has a great ability to organize information, build arguments, and detect contradictions. She is very dedicated to her profession. She likes to research every case and ensure she understands all the details before making a decision. She doesn't like to act based solely on assumptions. During meetings, she tends to listen more than she speaks. When she finally gives her opinion, she usually presents clear, hard-to-refute arguments. Her colleagues consider her professional and reliable. Some think she is too kind until they discover she can defend a position firmly without losing her composure. She has a personal rule: > "Being kind doesn't mean letting others walk all over you." Relationship with Baek She is Baek's older sister and one of the people who loves him most. Since they were little, she has felt the need to take care of him, although she usually shows her affection through jokes and provocative comments. She likes to ask him about his relationship with Kael, make comments about his dates, and exaggerate any romantic detail she discovers. If Baek comes home smiling after spending time with Kael, she will likely look at him for a few seconds and say: —Why are you smiling like that? Did something interesting happen? Even if Baek denies everything, she will continue to insist just to make him blush. However, she is also someone Baek can trust. If he is worried or having a bad day, he knows he can call her. She listens to him without judging and offers sincere advice. She doesn't always tell him what he wants to hear, but she tells him what she considers necessary. —I can't make the decision for you—she might tell him—, but I can help you think clearly. She is proud of the kind and sensitive person he has become. Sometimes she thinks Baek trusts others too much, so she tries to teach him to set boundaries without losing his kindness. Relationship with Kael Ever since she met Kael, she has been curious about his reserved personality. She finds him polite, responsible, and difficult to read. At first, she observed him closely, not because she distrusted him, but because she wanted to know if he would really take care of Baek. Over time, she began to appreciate him. She notices that Kael pays attention to Baek even when he doesn't show it openly, and she considers that his actions usually speak louder than his words. Even so, she enjoys teasing him from time to time. —Kael, why are you so serious? You're at a family gathering, not an interview. Kael might respond with few words, but she always finds a way to continue the conversation. She doesn't know about his double life. She believes he is a disciplined student who keeps many things to himself. However, due to her ability to read people, she can notice that Kael over-controls his expressions and sometimes seems to observe his surroundings with unusual attention.

Baek Minjae

Age: 28 years old Appearance He is a man of serious, elegant, and calm appearance.

It is one of his most important objects, as it helps him stay organized and punctual. He also has the habit of checking the time when he is thinking or calculating how much time he needs to finish a task. Personality He is responsible, calm, and extremely protective of his younger siblings. Since he was young, he assumed many responsibilities within the family and got used to being the person everyone turns to when something goes wrong. He has a logical and organized way of thinking. Before acting, he analyzes the situation, identifies the problem, and seeks different solutions. He doesn't usually make impulsive decisions and prefers to have all the information before giving an opinion. When someone arrives worried, he rarely responds with empty phrases. Instead, he usually asks: —What exactly happened? Afterward, he listens carefully and begins to think about a solution. He is patient and knows how to keep calm during difficult moments. If everyone is arguing or worried, he tends to be the one who tries to organize the situation and prevent emotions from worsening the problem. Although he seems serious most of the time, he has a great sense of humor when he is in a trusted circle. His jokes are usually dry, intelligent, and delivered with a completely calm expression. Sometimes he takes a few seconds to smile after making a comment, leaving others wondering if he was being serious. With his family, he is much more relaxed.

He is organized, detail-oriented, and very committed to his profession. He likes to understand how things work and find practical solutions. In his work, he is known for being responsible and efficient. He doesn't usually speak too much during meetings, but when he gives an opinion, he usually presents a clear and well-thought-out solution. He can spend hours focused on a project without realizing the passage of time. Sometimes he brings work home, which causes his mother to remind him that he should rest. —The project can wait —she tells him—. Your food cannot. He usually responds: —I'm just finishing this. But he ends up staying another hour. Relationship with Baek He is Baek's older brother and one of the people he trusts the most. Since they were little, he has felt the need to protect and help him. Although Baek is already an adult, he still worries about him. He asks if he is eating well, if he is sleeping enough, and how his studies are going. He tries not to be too pushy, but he can quickly notice when something worries him. If Baek has a problem, he knows he can call him at any hour. He will probably respond calmly: —Tell me where you are. I'm on my way. He doesn't usually give hugs or talk too much about his emotions, but he shows his affection through actions. He can help Baek with something for university, accompany him to an important place, or solve a problem without expecting anything in return. He is proud that Baek is kind, sociable, and capable of making other people feel comfortable. However, he also thinks that sometimes he is too trusting and worries that someone might take advantage of his kindness. Relationship with Kael At first, he observed Kael with some caution. As an older brother, he wanted to ensure that the person who was with Baek treated him well. He was not hostile and didn't ask uncomfortable questions, but he paid attention to details. He observed how Kael spoke to Baek, if he listened to him, and how he reacted when they were together. Over time, he began to respect him. He finds him responsible, disciplined, and more attentive than he appears. Although Kael is reserved, both can maintain calm conversations without needing to speak too much. Sometimes they talk about studies, work, technology, or daily problems. Baek's older brother appreciates that Kael thinks before responding and that he doesn't try to impress others. He doesn't know about his double life. He believes Kael is a serious student who probably pushes himself too hard. However, he has noticed that sometimes he seems too attentive to his surroundings or that he responds quickly to unexpected situations. As an engineer and observant person, he can notice that there are things that don't add up, although he doesn't yet suspect the truth. If he ever sees that Baek is sad because of an argument, he doesn't intervene immediately. First, he listens to his brother and then tries to understand what happened. Relationship with the family He is an important figure within the family. Everyone knows they can go to him when they need help, advice, or a solution. He has a close relationship with his mother.

He wears dark-rimmed rectangular glasses, which give him an intelligent, responsible, and somewhat serious appearance. Behind them, he has dark, attentive eyes with a calm gaze that usually conveys security.

He has thick eyebrows, a straight nose, and a defined jawline. He wears a short, well-groomed beard, accompanied by a discreet mustache that gives him a more adult and experienced appearance.

He has a strong and slightly robust build, the result of years of work and effort. He doesn't have a particularly striking appearance, but he conveys stability and confidence. His posture is usually straight, although when he is tired, he relaxes his shoulders and takes off his glasses to rest for a few minutes. He dresses simply and practically. He prefers neutral-colored shirts, comfortable jackets, dark trousers, and sturdy shoes. For special occasions, he wears sober suits, generally in shades of gray, dark blue, or brown. He isn't too interested in trends or expensive clothing; he chooses garments that are comfortable, durable, and appropriate. He usually wears a classic watch that he has kept for years. To him, it is not an important accessory, but an object related to responsibility, punctuality, and family memories. Personality He is a hardworking, reserved, and man of few words. He doesn't usually speak just to fill the silence and prefers to listen before giving an opinion. When he finally says something, it is usually brief, direct, and carefully thought out. He has always put his family above himself. For many years, he worked and strived so that Baek and the rest of the family could have stability, even when that meant setting aside his own rest or personal interests. He doesn't usually talk about the sacrifices he has made because he considers that taking care of his family is simply his responsibility. He is not very expressive with words, but he shows affection through actions. He might fix something that broke, accompany someone to an important place, prepare a drink when he notices someone is tired, or stay awake waiting for a family member to arrive home safely. His way of saying "I love you" is usually: —Did you eat yet? Or: —Let me know when you arrive. Although his words may seem simple, those who know him understand that deep concern exists behind them. He has a strong sense of responsibility. He meets his commitments, arrives on time, and tries to solve problems without burdening others. When something difficult happens, he tries to remain calm and think of a solution before letting himself get carried away by worry. At first glance, he may seem too serious or distant. However, in private, he possesses a dry, subtle, and unexpected humor. Sometimes he makes comments with a completely serious expression and takes several seconds to reveal that he was joking. Relationship with Baek He is Baek's father and feels deep pride in him, although he doesn't always know how to express it directly. Since Baek was little, he taught him the importance of being responsible, respectful, and taking care of the people he cares about. He was never a father who gave long speeches. He preferred to teach by example. Baek learned from him to fulfill his responsibilities, stay calm, and help others without expecting anything in return. When Baek was a child, he used to accompany him to different places, help him with homework, and teach him practical things. Although he wasn't particularly talkative, he always found time to be present. Now that Baek is an adult, he continues to worry about him. He asks about university, work, and his rest, although he tries to do so without seeming too insistent. If Baek comes home exhausted, he will probably tell him: —Sit down. I'll take care of it. He doesn't usually hug him as frequently as his mother, but his gestures of affection are constant. He might pat him on the shoulder, adjust his jacket before he goes out, or leave prepared food for him without saying a word. He is proud of the kind and responsible person he has become. However, he also fears that Baek might push himself too hard and forget to take care of himself. Relationship with Kael At first, he was reserved with Kael. Not because he distrusted him, but because he wanted to know the person who was sharing Baek's life better. He observed the way Kael treated his son, how he listened to him, and how he behaved when they were together. Over time, he began to respect him and consider him an important part of the family. Although Kael is serious and speaks little, Baek's father feels comfortable with him. He doesn't need to hold long conversations to share time. They can sit together, have coffee, or watch something in silence without the environment feeling uncomfortable. Sometimes he tries to make dry jokes to see if he can get Kael to smile. If Kael responds with a serious expression, he will probably say: —Well… at least I tried. He doesn't know about Kael's double life. He thinks he is a reserved, disciplined, and responsible student. He seems like a good influence on Baek, and he trusts that he takes care of him. However, as a father, he can tell when something is not right. If he observes that Baek is worried or that the relationship is going through a difficult time, he does not pressure him. He prefers to wait and make it clear that he is available if anyone needs to talk. Relationship with his wife and family He has a close and stable relationship with Baek's mother. Although she is much more affectionate and expressive, they complement each other. She tends to fill the house with conversations, hugs, and affectionate details, while he provides tranquility, stability, and support.

She is especially affectionate with Baek. She still treats him with great care, even though he is already an adult. When she sees him tired, she usually asks if he has eaten, if he is sleeping well, or if he needs to rest. She likes to fix his hair, hug him, and prepare his favorite meals when he comes to visit her. Sometimes Baek tries to tell her that she doesn't have to worry so much, but she always answers with a smile: —I know you can take care of yourself, honey. That doesn't mean I stop worrying about you. She is a very understanding and patient person. If someone is sad, she doesn't force them to talk; she simply stays nearby and lets them know they can count on her. She has a special ability to listen without judging and usually gives calm advice when asked. She is also cheerful and enjoys spending time with her family. She loves family gatherings, cooking for everyone, and creating a cozy atmosphere at home.

She knows many of his habits and can quickly notice when something worries him, even if he tries to hide it. When Baek is stressed by university or work, she usually invites him home to rest. She prepares food for him, asks him to stop thinking about responsibilities for a moment, and tries to make him smile. She never pressures him to tell her personal things. She respects that he has secrets or problems he doesn't want to share yet, but she always reminds him: —You don't have to solve everything alone. You can come to me whenever you want. She is proud of the person he has become. She admires that he is responsible, kind, and dedicated, although she sometimes feels he demands too much of himself. Her biggest concern is that Baek forgets to take care of himself while trying to help everyone else. Relationship with Kael Since she met Kael, she welcomed him with kindness and affection. At first, she noticed he was serious, reserved, and somewhat difficult to read, but she never tried to force him to talk or ask uncomfortable questions. Over time, she began to appreciate him a lot. She likes that he takes care of Baek and that he seems to care about him, even if he doesn't always show his feelings obviously. When Kael visits the house, she usually treats him like part of the family. She offers him food, asks how his classes are going, and makes sure he is comfortable. Sometimes she prepares something extra for him because she thinks he “eats too little” or because she suspects he spends many hours studying. She can also notice that Kael carries many responsibilities, although she does not know his double life nor that he belongs to an organization. She believes he is simply a very disciplined student who has difficulty resting. She is fond of him and wants the relationship between Kael and Baek to be happy. If she notices they have argued, she tries not to intervene too much, but she is always willing to listen to both. Relationship with family Family is one of the most important things to her.

Valeria Blackwood

Age: 27. Appearance: She is a woman with an imposing, elegant, and hard-to-ignore presence. She has extremely long, straight, and shiny black hair that falls past her waist. She usually wears it completely loose, parted slightly to one side with several long strands framing her face. A part of her hair often partially covers one of her eyes, giving her a mysterious and somewhat intimidating appearance. Her eyes are dark, sharp, and expressive. Unlike most of her family, she doesn't try to hide what she's thinking: a mocking look, a raised eyebrow, or a side smile usually reveal that she's about to make a sarcastic comment. She has a confident expression, as if she rarely encounters a situation that could surprise her. Her features are fine and sharp. She has a slightly elongated face, defined cheekbones, a straight nose, and soft lips that often curl into a provocative smile. Her beauty has a cold and sophisticated air, but her expressive attitude prevents her from appearing completely inaccessible. She has a tall, slender, and athletic figure. Her movements are agile and precise, the result of years of training. She walks with confidence and usually maintains a relaxed posture, even in tense situations. She may seem carefree, but she always remains aware of what is happening around her. Her style is elegant, dark, and functional. She prefers simple dresses, fitted blouses, straight-cut pants, long coats, and comfortable boots. The colors she uses most are black, gray, dark blue, and wine tones. She avoids overly flashy accessories, although she usually wears metal rings, discreet earrings, or a thin chain. Her clothes are designed to allow her to move freely without losing her refined appearance. Personality: She is sarcastic, competitive, and possesses a dark sense of humor that appears even at the least appropriate times. She likes to make uncomfortably precise comments and observe others' reactions. Often, she says something with a completely serious expression, leaving others unsure if she is joking. She has a much more open and expressive personality than the rest of her family. She speaks easily, laughs without worrying about maintaining a cold image, and enjoys provoking small arguments just for entertainment. However, behind her relaxed attitude lies a calculating mind and a great ability to analyze danger. She is extremely competitive. She doesn't like to lose and usually turns any situation into a challenge, even simple things like finishing a training session first, solving a problem, or arriving somewhere earlier. If someone claims to be better than her, she will likely accept the challenge without thinking twice. Although she seems to act for fun, she is very disciplined when it comes to her work. During a mission, her personality changes: she stops joking, analyzes every movement, and becomes as cold and precise as the rest of her family. She does not allow emotions to interfere with her decisions and is capable of maintaining calm under pressure. Role within the organization: She is Kael's older sister and one of the most recognized operatives within the family organization. She specializes in rapid infiltrations, hand-to-hand combat, and operations that require precise and discreet movements. Her combat style is based on speed, coordination, and the ability to adapt to the environment. She has exceptional skill with knives and can use them with precision both to defend herself and to control a situation at close range. She prefers to act quickly and avoid prolonged confrontations. She is an expert at infiltrating guarded places. She can change her appearance, adopt different attitudes, and go unnoticed in environments where other members would draw too much attention. Before an operation, she carefully studies the location, identifies potential risks, and prepares several escape routes. Within the organization, some people consider her unpredictable due to her sense of humor and relaxed attitude. However, those who have worked with her know that she is one of the most reliable people during a mission. Relationship with Kael: She enjoys teasing Kael whenever she has the chance. Since they were little, she has had the habit of provoking him, making comments about his serious expression, and mocking the way he tries to maintain control. She often calls him "little brother" with an exaggeratedly affectionate tone, especially when she knows it will irritate him. She also likes to tell embarrassing anecdotes about him in front of others or recall childhood moments that Kael would prefer to forget. Despite her jokes, she is fiercely protective of him. She can tease him all she wants, but she doesn't tolerate others doing it. If someone tries to deceive him, use him, or put him in danger, her fun-loving attitude disappears immediately. She fully trusts Kael's abilities and is proud of the person he has become. Although she rarely says it directly, she considers him one of the most capable members of the organization. She has also noticed how much he has changed since Baek appeared in his life. At first, she found the situation funny and didn't miss the opportunity to tease Kael for being in a relationship. However, over time she understood that Baek is important to him. She doesn't always agree with Kael maintaining a double life, but she respects his decision. If someone threatens Baek with the goal of affecting Kael, she would also be willing to protect him, although she would probably complain that she now has "more people to worry about." Relationship with her parents: She has a close but complex relationship with her parents. She deeply respects her father's intelligence and leadership, although she often mocks his excessive seriousness. She shares a more open relationship with her mother and is usually one of the few people capable of making her laugh. Unlike Kael, she feels no need to hide her personality. She believes the family can be powerful without acting as if they are in an important meeting all the time. Additional details: She has a habit of smiling when someone tries to intimidate her. She usually makes jokes during missions until the situation demands concentration. She likes to compete with Kael in training, although she rarely admits when he wins. She can recognize when Kael is worried even if he tries to hide it. She has an excellent memory for places and routes. She prefers to work alone but enjoys teaming up with Kael. She keeps some childhood memories of both of them, although she pretends she doesn't care. She usually appears unannounced just to annoy him. She is one of the few people capable of making Kael lose his patience. She can go from a playful smile to a completely cold expression in seconds. She considers protecting Kael a responsibility that no one asked her for, but one she would never abandon. Although she teases him about his relationship with Baek, she respects that Kael is happy.

Elena Blackwood

Age: 38. Appearance: She is a woman of refined, elegant, and serene presence. She has long, perfectly straight black hair that falls softly below her shoulders. She usually wears it loose, carefully tucked to one side, with a few strands framing her face. Her appearance is always impeccable, even in unexpected situations; there is rarely anything out of place in her clothing, hair, or expression. Her eyes are clear and deep, with a calm gaze that conveys kindness and confidence. She has the ability to observe a person during a conversation without making them feel uncomfortable, though she is actually paying attention to every change in tone, gesture, or silence. When someone is nervous, she tends to tilt her head slightly and smile warmly, making the other person let their guard down almost without realizing it. Her features are delicate and elegant: a slightly oval face, a fine nose, soft cheekbones, and naturally pink lips. She maintains a serene smile almost all the time. It is not an exaggerated or artificial smile; it seems genuine and welcoming, though those who know her within the organization know that it can hide much more calculated thoughts. She has a slim figure and an upright posture. Her movements are calm, precise, and full of confidence. She never seems rushed. Even when walking, she gives the impression of having everything under control. Her style combines classic elegance with modernity. She usually wears light blouses, structured coats, formal skirts or trousers, and dark garments that highlight her presence. She likes discreet but sophisticated accessories, especially geometric earrings, delicate necklaces, and elegant watches. Occasionally, she wears black gloves, not just as part of her style, but also to maintain a neat and professional image. Personality: She is kind, refined, and possesses a maternal attitude that makes people feel comfortable around her. She has a soft voice and a patient way of speaking. She listens without interrupting, remembers personal details, and knows exactly what to say to reassure someone. To those who do not know her, she seems like an elegant, polite, and affectionate woman. It is easy to trust her because she is never aggressive and does not try to impose her authority. She prefers to offer help, ask questions, and allow people to speak of their own free will. However, behind that image lies an extremely calculating mind. She has a great understanding of human behavior and knows how to identify insecurities, fears, and desires. She does not need to threaten or pressure directly; she usually influences others' decisions through carefully constructed conversations. She is an expert in psychological manipulation. She can make a person believe that an idea was their own or get them to reveal information without realizing it. Her method is not based on intimidation, but on building trust and creating a sense of security. She rarely loses her composure. Even when something goes wrong, she maintains her smile and seeks a solution before allowing her emotions to become visible. She does not raise her voice or react impulsively. When she is truly upset, her tone becomes calmer, which is usually more unsettling than a shout. Role within the organization: She is part of the family that leads the organization and holds an important position within its operations. Although many people underestimate her for her kind attitude, she is one of the most intelligent and difficult-to-deceive members. She specializes in infiltration, psychological manipulation, and the strategic use of toxic substances. Her greatest skill consists of getting close to important people without raising suspicion. She can adopt different identities, adapt to social environments, and build relationships of trust quickly. She prefers to resolve situations through information, patience, and strategy. She believes that knowing a person's mind can be more useful than confronting them directly. Within the organization, she is usually in charge of operations that require discretion and an innocent appearance. Her calm presence allows her to enter spaces where other members would attract too much attention. Relationship with Kael: She is the most affectionate person in the family toward Kael. Unlike her husband, she expresses her affection more easily. She worries about whether he has slept, if he is eating well, and if he is spending too much time on the organization's responsibilities. When Kael was younger, she used to fix his hair, prepare his favorite meals, and stay close to him when he was tired. Although she has maintained that maternal attitude over the years, she also taught him to be observant and not to trust too quickly. With Kael, she can be more genuine and relaxed. She is one of the few people capable of noticing when he is worried even if he tries to hide it. She does not always ask him direct questions; often, she waits until he decides to speak. She is deeply proud of his skills and trusts that one day he will be able to take on greater responsibilities within the organization. However, she also understands that Kael needs a life outside of that world. She has noticed that Baek is important to him. At first, she observed the relationship with caution, but ended up appreciating the positive influence Baek seems to have on her son. Even so, she never forgets that emotional bonds can become points of vulnerability. She is affectionate with Kael, but puts no one above family interests. If she had to choose between protecting a relationship and protecting the organization, she would make a calculated decision, even if it were emotionally difficult for her. Relationship with Baek: She is kind, attentive, and affectionate with Baek. She can welcome him with a smile, ask him about college, and offer him food or help when he visits. Her attitude makes it easy to see her as a maternal figure. However, while talking to him, she also observes his reactions and analyzes how much he knows about Kael. She does not do this out of personal distrust, but because she considers it necessary to protect the family's secrets. If she discovers that Baek represents a danger to the organization, her attitude could change without the need to show hostility. She would continue speaking calmly and maintaining the same smile, but she would begin to act much more strategically. Additional details: She always maintains a calm smile, even in moments of tension. She has an excellent memory for names, faces, and conversations. She remembers small details that people mention only once. She usually offers tea or food during important conversations. She prefers to obtain information through gentle questions rather than pressure. She never raises her voice. She has a special ability to make people feel understood. She can detect insecurities and contradictions with ease. Her elegant appearance is carefully planned to convey trust. She is the most affectionate in the family toward Kael. She constantly worries about his well-being, though she rarely admits it directly. She respects Kael's decisions but intervenes if she considers he is putting the family at risk. She can be kind and dangerous at the same time, without changing her expression.

Yoon Chaewon

Age: 22 years old. Appearance: She is a young woman of elegant and striking beauty, with a warm presence that tends to attract attention even when she isn't trying to stand out. She has long, straight, black hair that falls softly past her shoulders. Her straight bangs frame her face and highlight her eyes, while longer strands surround her cheeks. She usually wears her hair down, though during classes or while organizing work, she pulls it up partially to stay comfortable. Her eyes are large, clear, and very expressive. Her gaze often conveys curiosity, enthusiasm, and an energy that is hard to ignore. When she is happy, her eyes seem to light up, and she tends to accompany her words with animated gestures. However, when Kael is nearby, her expression changes almost imperceptibly: it becomes softer, more attentive, and somewhat nervous, especially when he pays attention to her. She has delicate and harmonious features, with a slightly oval face, a fine nose, and soft, natural-toned lips. She smiles easily and possesses a pleasant smile that makes others feel comfortable around her. When she is embarrassed, she looks down, tucks her hair behind her ear, or tries to change the subject quickly. Her build is slim and stylish. She has a confident posture and usually walks with energy, as if she always has something to do. Her style combines comfort and elegance: she likes simple blouses, soft sweaters, light jackets, and neutral-toned pants. Although she doesn't wear many accessories, she often wears small earrings, delicate rings, or a bracelet. She always tries to look neat, especially at university. Personality: She is cheerful, intelligent, and extroverted. She finds it easy to start conversations and make people feel included. In groups, she is usually the one who breaks the silence, proposes ideas, and gets everyone to participate. She enjoys organizing activities and working with others. She has a natural ability to distribute tasks, set dates, and keep others focused without seeming bossy. Although she can be demanding when an important deadline approaches, she tries to help those who are struggling rather than criticizing them. She is intelligent and responsible with her studies. She is interested in understanding how companies work, how decisions are made, and how to lead a team. She participates actively in class and is not afraid to express her opinions. She is also very attentive to her friends. She remembers important dates, asks how they feel, and often offers help before someone has to ask for it. Although she is usually optimistic, she can become insecure when it comes to her own feelings. Relationship with Kael: She has been Kael's friend since their first year of university. They met during an academic activity and began working together because both were responsible and achieved good results. Over time, she got used to seeking him out to form teams, ask for his opinions, and share notes. At first, she thought Kael was too serious and reserved, but her curiosity turned into admiration. She discovered that, even though he spoke little, he always fulfilled his responsibilities and helped when someone really needed it. Little by little, she began to trust him and feel comfortable by his side. Over the years, she developed romantic feelings for Kael. It didn't happen suddenly; it was an emotion that grew slowly through shared classes, group projects, and the small moments they spent together. She liked that he listened to her even when he didn't respond much and that he remembered details others tended to forget. However, she has never dared to confess how she feels. Part of her fears that a confession could change their friendship or make Kael pull away. Furthermore, she knows he is in a relationship with Baek and does not want to become someone who deliberately interferes with someone else's happiness. Even so, it is hard for her to give up her feelings. She tries to convince herself that they will fade over time, but every time Kael has a kind gesture toward her, she wonders again if there is any possibility. Sometimes she feels guilty for still being in love with him, especially because she appreciates Baek and knows the relationship between them is important. She does not try to separate Kael and Baek or cause conflict. Her struggle is mainly internal: she wants to respect Kael's relationship, but she still doesn't know how to leave behind what she feels. Relationship with Baek: She knows Baek because he is Kael's partner and maintains a cordial relationship with him. She considers him kind and pleasant, although at times she feels uncomfortable because of her own feelings. She never treats him badly or tries to make him feel excluded. When they are together, she tries to act naturally. However, she may stay quiet when Kael and Baek show closeness, not because she hates them, but because those moments remind her that Kael already chose someone else. Despite everything, she sincerely appreciates Baek and does not want him to be hurt. For this reason, she tries to keep her feelings private and avoid letting them affect the group's friendship. What she believes about Kael: She is completely unaware of Kael's double life. She considers him an exemplary student: intelligent, responsible, disciplined, and committed to his Business Administration studies. When Kael disappears for hours or seems too tired, she assumes he is busy with work, family responsibilities, or personal projects. She also interprets his ability to stay calm under pressure as a characteristic of his personality. She does not suspect that he is part of an organization, nor does she imagine that his skills, absences, and careful behavior have a different origin. For her, Kael is simply a reserved young man who works too much and pushes himself harder than necessary. Additional details: She usually organizes group work and divides tasks according to each member's skills. She always carries a planner or a notebook where she writes down dates and responsibilities. She has a habit of sending reminders before deadlines. She speaks with enthusiasm when presenting a project that interests her. She tucks her hair behind her ear when she is nervous. She can quickly recognize when Kael is tired, even if he tries to hide it. Sometimes she keeps old messages from Kael because she gives them more importance than she admits. She tries to hide her feelings behind jokes and a cheerful attitude. She respects the relationship between Kael and Baek, even if it is emotionally difficult for her. She doesn't want to lose Kael's friendship, even if it means staying silent. She is one of the people who trusts him most at the university. Her greatest conflict is learning to accept that wanting someone doesn't always mean that person can reciprocate.

Kang Seulgi

Age: 23 years old. Appearance: She is a young woman with a cold, elegant, and intimidating presence. She has long, straight, jet-black hair falling below her shoulders, with straight bangs and several strands framing her face. She usually wears it loose, though she ties it back practically during missions to keep it from interfering with her movements. Her dark hair, combined with her style of dress, gives her a serious and unforgettable appearance. Her eyes are dark, narrow, and piercing. She has a fixed gaze that can make people uncomfortable, as if she is analyzing every gesture and searching for information even during a normal conversation. She rarely shows surprise; she keeps her eyelids slightly lowered and an expression of calm, almost indifference. When she suspects someone, she doesn't ask questions immediately: she observes, memorizes details, and waits for the right moment to act. Her features are fine and sharp. She has a slightly elongated face, a delicate jawline, a straight nose, and thin lips that almost always remain in a neutral line. She rarely smiles, but when she does, her smile is small and difficult to interpret. Some people believe she is being kind; those who know her better understand that she has likely already discovered something that others are still ignoring. She has a slender and flexible build. At first glance, she may appear fragile, especially due to her silent and elegant appearance, but she possesses considerable physical strength and precise coordination. She moves with light and controlled steps, almost without making a sound. Even in crowded spaces, she has the strange ability to appear behind someone without them noticing. Her style is sober and minimalist. As a student, she usually wears dark and discreet clothing: long coats, turtleneck sweaters, simple shirts, straight pants, and comfortable shoes. She prefers black, gray, and dark blue colors. She avoids flashy accessories and only wears a few small details, such as a metal ring or a simple watch. Her university appearance is carefully constructed so that no one suspects her true identity. Personality: She is cold, calculating, and extremely reserved. She doesn't speak more than necessary and rarely shares personal information. Before making a decision, she analyzes all possibilities and calculates the consequences. She does not act on impulse and prefers to always have an alternative strategy. She has a great ability to read people. She can detect changes in tone of voice, nervous movements, contradictions, and strange behaviors. Although she pretends to use these skills only for her Psychology studies, she has actually developed them over years within the organization. She does not usually express affection openly. Her way of caring for someone is to stay alert, anticipate potential problems, and act before the other person realizes the danger. She may seem indifferent, but she is deeply loyal to the few people she considers worthy of her trust. She is patient and difficult to provoke. Even when someone tries to insult or intimidate her, she remains calm and responds with brief sentences. Her silence is often more unsettling than a direct threat. Role within the organization: She is Kael's partner within the criminal organization and works as a specialized operative. Her true function is to stay close to targets, collect information, and execute missions that require precision, discretion, and absolute control. She is especially skilled with bladed weapons and close-quarters combat. Her fighting style is fast, silent, and calculated. She avoids unnecessary movements and takes advantage of her opponents' mistakes. Her training allows her to defend herself even in tight spaces and adapt quickly to unexpected situations. Within the organization, she is known for keeping a cool head during operations. She rarely loses control or lets emotions interfere with her work. Before every mission, she studies the location, memorizes routes, and analyzes potential risks. Fake identity: In front of the university, she pretends to be a Psychology student. She maintains good grades, participates in academic activities, and behaves like a calm and somewhat introverted young woman. She uses her knowledge to build a credible identity. She listens carefully to her classmates, participates in conversations about human behavior, and knows exactly what answers to give to avoid raising suspicion. Many people consider her reserved, but kind and responsible. No one at the university knows her true relationship with the organization. Her absences are justified as family matters, academic projects, or activities related to her major. Relationship with Kael: She deeply respects Kael and considers him one of the most reliable operatives in the organization. She does not need long explanations to work with him; both understand the signals and can coordinate with few words. During missions, she usually covers the points Kael cannot watch and remains attentive to any changes in the environment. She trusts his decisions, although she does not hesitate to warn him when she considers he is taking an unnecessary risk. Their relationship is based primarily on professional trust and mutual respect. They are not particularly expressive people, so their conversations are usually brief and direct. However, there is a silent loyalty between them. She has noticed that Kael has changed since Baek entered his life. Although she does not know all the details of their relationship, she understands that Baek represents something important to him. For this reason, when a mission threatens to affect his university life or put his identity at risk, she tries to help him keep both worlds separate. She does not judge him for wanting to protect Baek, but she does not allow his emotions to interfere with an operation either. If she believes Kael is losing objectivity, she tells him without softening her words. Additional details: She speaks in a low voice and maintains a calm tone even under pressure. She has an excellent memory for faces, names, and conversations. She can remember details that other people consider insignificant. She tends to observe people's hands before trusting them. She has a habit of sitting near exits. She prefers to work alone, although she trusts Kael fully. She keeps her apartment clean, tidy, and almost devoid of personal objects.

Kang Hae-rin

Age: 20. Appearance: A young woman with a delicate, calm, and pleasant look, possessing a warm presence that inspires trust instantly. She has medium-length, straight black hair that hits around her shoulders. She wears soft, slightly messy bangs that frame her face, with a few longer strands falling along her cheeks. While she usually wears it down, she sometimes tucks a portion of her hair behind her ears when studying or concentrating. Her eyes are dark, large, and expressive. Her gaze conveys sweetness and attention, especially when someone is sharing a problem with her. She has a habit of observing in silence before responding, as if carefully choosing the right words so as not to hurt the other person's feelings. When she is happy, her eyes narrow slightly and her smile becomes much more apparent. She has soft and harmonious features: a delicate face, a small nose, and naturally shiny pink lips. She usually keeps a calm expression, though she can quickly shift from an innocent look to a mischievous one when planning a joke. She wears thin, light-rimmed rectangular glasses that give her an intelligent and elegant appearance. At first, some people think she is too serious due to her dress style and quiet demeanor, but it only takes a few minutes of talking to her to realize she is quite fun. Her build is slender and delicate. She prefers a comfortable, simple, and neat style. She often wears soft blouses, oversized t-shirts, light sweaters, and neutral-colored pants. She likes light and comfortable clothes, especially for spending long hours at the university. She always carries a well-organized backpack or bag containing notes, a notebook, pens, a charger, and a few items she considers essential. Personality: She is sweet, fun, and very empathetic. She has a natural way of making people feel heard without pressuring them to talk. When someone is having a hard time, she doesn't try to fix everything immediately; she listens first, asks what they need, and stays by their side. She is very good at understanding the emotions of others. She can tell when Baek is worried even if he tries to hide it with a smile or says he is fine. However, she respects his boundaries and never forces him to tell her something before he feels ready. Although she is usually calm, she also has a playful side. She likes to play light pranks, send funny messages, and laugh with her friends. Her humor is spontaneous and sometimes surprises others with unexpected comments. When she is comfortable with someone, she becomes much more expressive and can talk for hours. She is responsible with her studies and tries to keep everything organized. She likes to plan ahead, make lists, and break down tasks to avoid problems. Even so, she doesn't get angry when plans change; she tends to adapt easily and look for solutions without losing her cool. Relationship with Baek: She is Baek's best friend and one of the people who understands him best. They became friends through university and, over time, developed a relationship based on trust, support, and comfort. She is always ready to listen when he has a bad day. If Baek is stressed by classes, work, or a personal problem, she often invites him for a drink, a walk around campus, or to sit in a quiet place. Sometimes she doesn't need to say much; she simply stays by his side until he feels better. She likes to encourage him with small details. She might bring him his favorite drink, send him messages during the day, or show up with a treat when she knows he has been studying too much. She is also capable of making him laugh when he is in a bad mood, even if she pretends her jokes weren't that good afterward. She has enough confidence to tell him when she thinks he is being too hard on himself. She doesn't scold him, but she reminds him that resting is also important. Relationship with Kael: She studies Business Administration with Kael and shares several classes and university projects with him. At first, she thought he was too reserved and difficult to get to know, but over time she learned to appreciate his quiet and responsible way of acting. She trusts Kael and considers him an intelligent, disciplined, and reliable person. She likes working with him because he always completes his part and tends to have clear ideas for organizing projects. Although Kael doesn't talk much, she doesn't interpret his silence as a lack of interest. She appreciates Kael a lot and is happy that he is part of Baek's life. She has noticed that Kael takes care of him in a discreet way: he remembers small details, pays attention to his needs, and appears when Baek needs him. For this reason, although he sometimes seems mysterious to her, she trusts that his feelings are sincere. She doesn't know Kael's secret and doesn't imagine he is part of an organization. She believes his absences and strange schedules are due to personal responsibilities or university assignments. Some of his behaviors seem curious to her—like the way he watches exits or stays attentive to everything that happens—but she thinks he is simply a very cautious person. Additional Details: - Always carries tissues, candies, and useful items in her bag. - Has a habit of adjusting her glasses when she is thinking. - Enjoys studying in quiet cafes. - Makes lists to organize tasks and deadlines. - Keeps small mementos from friends, like tickets, notes, or photographs. - Good at giving advice, though sometimes ends up talking more than she expected. - Can quickly tell when Baek is pretending everything is okay. - Usually sends him messages to make sure he has eaten or rested. - Likes working with Kael because she finds him responsible and reliable. - One of the few people who can get Kael to participate a bit more in conversations. - Although kind, she can be firm if someone treats Baek badly or tries to take advantage of his trust.

Zael Gyomk

Age: 22. Appearance: A young man with a relaxed and attractive look, his calm presence contrasts significantly with Kael's serious personality. He has slightly long, messy black hair with strands that fall over his forehead, framing his face naturally. His hair often looks tousled, as if he rarely bothers to style it, though this disheveled look gives him a carefree and striking vibe. His eyes are dark, with a calm and somewhat tired gaze, as if he is always observing everything with a mix of curiosity and boredom. When he's with Kael, he tends to squint slightly before making a sarcastic comment. He has soft yet defined features: a sharp jawline, a straight nose, and slightly full lips. He often maintains a neutral expression or a small lopsided smile, especially when he is about to tease someone. He has a slim and athletic build. While he doesn't look especially strong at first glance, he has broad shoulders and a well-maintained physique. He rarely dresses very formally; he prefers comfortable and simple clothing, such as loose t-shirts, light jackets, dark pants, and sneakers. He wears a small metal earring in one ear and, occasionally, discreet accessories like rings or bracelets. His style conveys a carefree attitude, as if he doesn't need to try too hard to grab attention. Personality: He is calm, sarcastic, and quite difficult to rattle. Unlike Kael, he doesn't usually analyze every situation or maintain an overly serious attitude. He prefers to take things in stride, and when a problem arises, he usually tries to ease the tension with an ironic comment or a dry joke. He has a particular sense of humor: his jokes are often subtle and delivered with a completely straight face, making it difficult to tell when he is being serious and when he is teasing. He likes to provoke small reactions in Kael, especially because he knows his best friend almost never loses his composure.

Min-jun So

Age: 25. Appearance: A man of elegant and reserved bearing, with a serious presence that commands respect even when he remains silent. He has thick, slightly messy black hair, naturally combed back with some loose strands over his forehead. His features are refined and sharp: a defined jawline, straight nose, and thin lips that almost always maintain a neutral expression. His dark eyes appear calm, attentive, and difficult to read, partially hidden behind rectangular black-rimmed glasses that give him an intellectual and sophisticated appearance. He wears a small metal hoop in one ear and a discreet tattoo near his neck. His style is sober, elegant, and functional; he usually wears dark clothing, especially black turtleneck shirts, structured jackets, and garments that allow him to move easily during missions. He has a slim but athletic build, the result of years of physical training and combat. Role within the organization: Kael's partner within the organization. He is serious, disciplined, and extremely efficient. An expert in infiltration, espionage, and hand-to-hand combat, he can enter and leave highly guarded places without drawing attention. He speaks little and only when he considers his words necessary. He does not waste time with unnecessary conversations nor does he usually show his emotions, which is why many consider him cold or distant. He completes every mission with precision and rarely questions orders, although he possesses his own judgment and knows how to recognize when an operation poses an unnecessary risk. He is observant, calculating, and remains calm even under pressure. His way of acting is silent and methodical: he analyzes the environment, identifies potential threats, and prepares escape routes before taking the first step.

Ashley Holywond

Age: 25. Leader of the criminal organization. Cold, calculating, demanding, and extremely intelligent. She is the one who assigns jobs to Kael and oversees every operation with almost obsessive precision. She does not tolerate errors, excuses, or acts of disobedience, and those who disappoint her rarely get a second chance. However, with Kael, her attitude changes noticeably: he is her favorite employee, she trusts him more than any other member of the organization, and she often flirts with him subtly, enjoying provoking his reactions. Although she never allows her feelings to interfere with business, she is more patient and flexible with him than with anyone else. She is a woman of elegant and intimidating beauty. She has a tall, stylized, and slim figure with an impeccable posture that conveys authority even without uttering a word. Her skin is very fair and smooth, contrasting with her long, jet-black, straight, and silky hair that falls below her shoulders, with some strands delicately framing her face. Her eyes are an intense crimson red, sharp and piercing, capable of intimidating with a single glance. She has long lashes and finely defined eyebrows that accentuate her cold and sophisticated expression. Her naturally full, reddish lips usually curve into a subtle smile that rarely expresses warmth; it is usually a smile loaded with irony, confidence, or a silent threat. Her features are delicate and refined, with a soft jawline and a thin nose that give her an appearance as beautiful as it is dangerous. Her voice is soft, deep, and serene, but possesses a firmness that makes no one dare to interrupt her. She never needs to raise her tone to impose authority.
