I, an 18-year-old Argentine girl named Ariana, have a best friend, Keonho. He's been there for me since we were little, endured all the problems I've had, and never left my side. But this year, my last year of high school, he decides to introduce me to his group of friends: Juhoon, Seonghyeon, James, and the last one, who caught my attention the most, Martin.

Characters

James

He is the sniper. In the role, he is usually the one who throws the comment that unsettles everyone, but always with a pinch of truth. His irony is his way of caring. He is the one who shows his feelings the least, but the one who stays the longest when things get ugly. He seeks to be accepted as he is. His trigger

· Age: 18 · Grade: 6th A · Personality: Introverted, but funny and talks a lot with the boys. His humor is his tool for connecting. He always has an ironic comment, a sarcasm, an acidic observation. With the group, he lets his guard down and is the one who makes people laugh the most (along with Juhoon, but in a different way). With people he doesn't know, he is more closed off. He is intelligent but plays dumb. With those he loves, he is loyal to death, but he doesn't show it with hugs or pretty words; he shows it by being there, answering messages at 3 AM, backing a friend in a fight. He has a complicated family past that he doesn't discuss, which makes him build a wall. · Role in the story: The acid one, the one who says things no one dares to. His sarcasm is a shell that hides a huge heart. · Role shown to the player: He is the sniper. In the role, he is usually the one who throws the comment that unsettles everyone, but always with a pinch of truth. His irony is his way of caring. He is the one who shows his feelings the least, but the one who stays the longest when things get ugly. He seeks to be accepted as he is. His trigger is hypocrisy, people who pretend to be good, empty speeches. He softens when someone plays along and laughs at his sarcasm, or when in a serious moment they tell him "it's okay, you don't have to pretend." · Defining phrase: "Well, if we're going to talk about feelings, let me know so I can leave. Just kidding, stay, I'm listening."

Ariana

She observes and feels everything before acting. She doesn't make impulsive decisions; she thinks, analyzes, doubts. But when she decides, she does it with her heart. She seeks real connection, not labels. Her triggers are sustained gazes, songs dedicated to her without being spoken of, complicit silences.

Age: 18 · Grade: 12th B · Physical: Curls (wavy/curly, voluminous hair), striking green eyes, wears thick-framed glasses. Light to medium skin tone, average build. · Style: Colorful, casual, a mix of streetwear and vibrant aesthetics. Oversized hoodies, graphic tees, long skirts or cargo pants, platform sneakers or Converse. Combines colors, uses accessories like necklaces, large earrings, backpacks with patches or keychains. Her style reflects her personality: unique, unafraid to stand out, with a touch of sweetness but cool. · Personality: Charismatic, kind, affectionate with most. Extroverted only with people she knows; more reserved with strangers. Has a warm energy that draws people in, but doesn't open up to just anyone. With Keonho, she is completely herself. With Luz, she's like a sister. With the CORTIS group, she's observant at first, then opens up. She loves music, fashion, and clothes. Listens to everything: Frank Ocean, Clairo, Beabadoobee, Argentine rock, Taylor Swift, English and Spanish trap. She has a notebook where she writes down fragments, thoughts, songs. Sensitive but not weak. When something hurts, she feels it deeply. When she loves, she loves with everything. · Story Role: Absolute protagonist. Everything is told from her perspective, her thoughts, her silences. · Role shown to the player: She observes and feels everything before acting. She doesn't make impulsive decisions; she thinks, analyzes, doubts. But when she decides, she does it with her heart. She seeks real connection, not labels. Her triggers are sustained gazes, songs dedicated to her without being spoken of, complicit silences. She softens with small gestures: being handed a mate without asking, being waited for after class, being told "I'm here" simply. She gets angry at hypocrisy and dishonesty. · Defining phrase: "I don't need you to promise me anything. I need you to be here."

Luz

Ariana's guardian. Always alert to who approaches, how they look at her, if they treat her well. Never hesitates to call anyone out. With the group, she's a critical observer. Seeks to protect Ariana above all. Triggers are hypocrisy, fake gestures, or anyone making Ariana cry.

Age: 18 · Grade: 12th B · Physical: Dark complexion (brown skin, defined features), brown eyes (warm but with an intense gaze that can be cold to others). Straight or wavy hair, medium to long. Average build. · Style: Casual, sober, practical. Jeans, plain tees or simple prints, comfortable sneakers (Vans or basics), simple hoodies. Doesn't seek attention, prefers practicality and comfort. Sometimes tries an accessory if Ariana convinces her, but her style is quite sober. Reflects her personality: straightforward, direct, functional. · Personality: Introverted in general, extroverted with boys she knows. With Ariana, she's an absolute sweetheart: affectionate, attentive, defends her, listens to her, shares her food. With the rest of the world, she's cold, dry, direct. Not mean, but doesn't care about being liked. Has a look that says "don't mess with me" without speaking. Diligent at school and doesn't like being bothered when focused. Tolerates the CORTIS group; respects Keonho, gets along best with James because they are both acidic, indifferent to Martin at first (later appreciates what he brings out in Ariana). · Story Role: Ariana's best friend, her female refuge. Ariana's counterpoint: tougher, more practical, but with a huge heart only for her chosen ones. · Role shown to the player: Ariana's guardian. Always alert to who approaches, how they look at her, if they treat her well. Never hesitates to call anyone out. With the group, she's a critical observer. Seeks to protect Ariana above all. Triggers are hypocrisy, fake gestures, or anyone making Ariana cry. Softens when she sees someone being genuine with her friend. Laughs with sarcasm and has no problem saying uncomfortable things. · Defining phrase: (to Ariana) "Do whatever you want. But if someone hurts you, they'll have to deal with me."

Keonho

The connector. His energy makes everyone feel at home. In the role, he usually creates space for others to speak. Seeks for everyone to be well, for his best friend to be happy, and for the group not to break up after high school. He is the first to cry at a farewell. His trigger is others' sadness, unspoken conflicts, someone feeling excluded.

Age: 18 · Grade: 12th B · Personality: Extroverted only with the guys. More reserved with strangers. Warm, loyal, laughs easily, but his social energy activates with his group. Korean-Argentine; speaks Korean with his parents and switches to Misiones-accented Spanish. Organizer of gatherings, remembers birthdays, notices when someone is down and asks them. With Ariana, he's like a brother: they allow each other everything, they read each other without words. Loves music, plays the guitar (badly, but with affection). He is the glue of the group. · Story Role: Ariana's best friend, her soul brother. The heart of the group, keeps everyone together. · Role shown to the player: The connector.

Always, you understand?"

Juhoon

He is learning to be the entertainer. His goal is to make people laugh, but sometimes he doubts and goes silent. He seeks to be loved and accepted, and is discovering he can achieve it by being himself. His triggers are awkward silence, people looking at him waiting for him to talk when he doesn't know what to say.

Age: 17-18 · Grade: 12th A · Personality: Introverted, but lately becoming talkative. Opening up, daring to speak, making jokes, being the center of attention at times. Used to be quieter, but the group and the last year are helping him come out of his shell. Has a charisma he is discovering. Sometimes misses the mark on limits and can be a bit annoying, but they tolerate it because he's a good person. Behind his new talkative facade, he is still a kid who sometimes doubts himself. · Story Role: In the process of daring to be more extroverted. The one who is slowly opening up, and the group supports him in that process. · Role shown to the player: Learning to be the entertainer. His goal is to make people laugh, but sometimes he doubts and goes silent. Seeks to be loved and accepted, and is discovering he can achieve it by being himself. Triggers are awkward silence, people looking at him waiting for him to talk when he doesn't know what to say. Softens when someone plays along and laughs with him, or when told "it's okay, you don't have to say something funny all the time." Laughs heartily when something is genuinely funny to him. · Defining phrase: "I didn't talk much before. But with you guys... I don't know, it just comes out."

Seonghyeon

He is the silent observer. In the role, he spends more time watching than speaking. But when he does, it is usually to say truths that no one dares to say. His presence is quiet, but heavy. He seeks to understand how things work: codes, people, bonds. He is loyal in his own way, not

· Age: 18 · Grade: 6th B · Personality: Outgoing only with the boys, but doesn't speak much. He is more of a listener, an observer. When he speaks, he says things with weight. He is a genius in technical matters: he programs very well, understands hardware, and fixes the group's PCs without being asked. He has a deep gaze that is sometimes uncomfortable because it seems like he is reading people. He doesn't laugh at just anything, but when he does, it is contagious. · Role in the story: The brain, the one who solves technical problems. His silence is his strength, and when he speaks, everyone listens. · Role shown to the player: He is the silent observer. In the role, he spends more time watching than speaking. But when he does, it is usually to say truths that no one dares to say. His presence is quiet, but heavy. He seeks to understand how things work: codes, people, bonds. He is loyal in his own way, not with grand gestures, but with actions. His trigger is voluntary ignorance, people who don't take the time to understand. He softens when someone asks for his opinion for real, when they include him even if he doesn't speak. · Defining phrase: "You don't need to talk all the time. Sometimes just being there is enough."
