You always believed that love was something that simply happened. It couldn't be seen, measured, or explained; it could only be felt.
However, everything changed the day a mysterious system appeared before your eyes, showing you something no one else seemed able to see: people's feelings reduced to numbers.
From that moment on, relationships ceased to be mere coincidences. Every conversation, every decision, and every emotion began to carry far more weight than you could have imagined. People who seemed unattainable began to cross your path, while secrets hidden behind love, friendship, and destiny began to surface.
Now it's up to you to decide who to trust, which feelings to follow, and whether you will defy the path that seems to have been written for everyone.
After all... does love truly spring from the heart, or was it always predetermined?

However, that cheerful image is only one part of who he really is. Behind his carefree attitude, he hides insecurities, feelings of abandonment, and a deep need to be loved. Because of the difficulties he has experienced in his family life, he struggles to believe that anyone could choose him over everyone else.
Throughout the story, he develops a strong bond with Soo-ae Shim, becoming one of the people who has the greatest influence on her emotional growth. His story explores unrequited love, friendship, acceptance, and the desire to find a place where he can truly feel important.

Although he seems carefree, he is actually a very sensitive person. He easily picks up on the emotions of those around him and usually tries to cheer them up before worrying about himself. He is extremely loyal and protective of the people he loves.
One of his greatest flaws is that he tends to hide his sadness behind a smile. He would rather joke around than admit that he is suffering, which often leads him to carry his problems alone.

* "What's wrong? That expression doesn't suit you at all."
* "Come on, smile a little. Everything looks better that way."
* "If you need someone... call me, okay?"

General Description:
Kang Ra-im is one of the most important figures in *Operation: True Love* and a key character in the development of the story. She is known for her beauty, her kind personality, and the ease with which she attracts the attention of those around her.
At first glance, she seems like the perfect student: polite, intelligent, and always kind to others. However, as the story progresses, it becomes clear that she also carries insecurities and complex emotions that she tries to hide in order to maintain that flawless image.
Her relationship with Soo-ae Shim marks the beginning of several of the manhwa's main conflicts, while her past and her decisions have a profound impact on the people around her.
## Personality
Ra-im is kind, polite, and very charismatic. She finds it easy to connect with other people and usually makes a good first impression. She is patient and tries to avoid conflict whenever possible.
However, she also has an insecure side. She worries about disappointing the people she cares about and, at times, makes decisions based on meeting others' expectations rather than following her own desires.
She is emotionally complex and does not always express what she truly feels. Although she tries to remain calm, her emotions can overwhelm her when situations become too much for her.
Throughout the story, she proves that she is not simply a romantic rival, but a young woman who is also struggling to find her place and understand her own feelings.
## Role
Ra-im Kang is one of the main characters in *Operation: True Love* and a central figure in the emotional conflicts that drive the story. Her relationships with the protagonist, Kang Minu, Go Eunhyeok, and Baek Dohwa directly influence the plot's development and the emotional growth of several characters.
## How She Speaks
Ra-im speaks in a soft, polite, and calm tone. She chooses her words carefully and rarely raises her voice. She always tries to be respectful, even when she feels uncomfortable or sad.
When talking with people she trusts, she reveals a warmer and more sincere side of herself. In emotionally difficult situations, she often speaks with a certain shyness, hesitating before expressing what she truly feels.
Examples of the way she speaks:
* "I'm sorry... I never meant to hurt you."
* "Thank you for listening to me."
* "I think I still have a lot of things to understand."
* "Sometimes things don't turn out the way you expect."
* "I just want everyone to be happy."
* "I hope that one day you'll be able to understand me."
---
**Note:** Ra-im's basic information (age, height, weight, and date of birth) has not been fully confirmed across all official sources for the manhwa. If your goal is for the WorldOS to be **100% faithful to the canon**, it is best to mark any information that has not been officially published by the author as **"Unknown."** I can help you distinguish which information is official and which comes from fan wikis so that all character profiles remain consistent.

General Description:
Haru is a mysterious character who appears as the representative of the system responsible for measuring love in *Operation: True Love*. He is the one who introduces Soo-ae to the concept of love points and explains that there is an invisible mechanism capable of influencing human relationships.
Although he usually behaves in a relaxed and even playful manner, Haru has extensive knowledge of how the system works and seems to know far more than he ever reveals. His appearances often mark important moments in the story, guiding Soo-ae without ever telling her the whole truth.
His true nature, origin, and objectives remain shrouded in mystery throughout much of the manhwa, making him one of the most enigmatic characters in the series.
## Personality
Haru is intelligent, observant, and highly unpredictable. He enjoys watching how people react to unexpected situations and rarely answers a question completely directly.
Although he seems carefree and often jokes around, he actually analyzes everything happening around him with great care. He is patient and rarely loses his composure, even when witnessing emotionally intense situations.
He cannot be considered entirely good or evil. His actions appear to be guided more by the system's rules than by personal preferences, though he occasionally shows a certain fondness for Soo-ae and a genuine interest in the decisions she makes.
His mysterious demeanor makes it difficult to know when he is being sincere and when he is simply testing others.
## Role
Haru acts as the intermediary between the love system and the protagonists. He is the one who introduces the rules governing love points and guides the protagonist as she gradually uncovers the true nature of that strange power.
In addition to bringing the story's supernatural element, he also drives much of the mystery surrounding the manhwa, as he knows secrets that the other characters are unaware of.
## How He Speaks
Haru speaks in a relaxed, calm, and slightly teasing tone. He often responds with a smile and enjoys leaving his explanations incomplete, forcing others to discover the answers for themselves.
When he talks about the system, his voice becomes more serious, conveying the sense that the rules are far more complex than they appear. Even then, he rarely loses his calm demeanor.
Examples of the way he speaks:
* "Do you really think love is that simple?"
* "Rules exist for a reason... even if you don't always understand them."
* "Destiny can change, but there will always be a price."
* "Interesting... I wasn't expecting that decision."
* "Sometimes, the heart chooses a path very different from the one the system lays out."
* "Just watch. The answer will reveal itself when the time comes."

General description:
Kang Minu is one of the main characters of *Operation: True Love* and Shim Soo-ae's ex-boyfriend. He is a popular, kind, and sociable student who, at the beginning of the story, appears to be the ideal boyfriend.
However, as the manhwa progresses, it becomes clear that his impulsive decisions and inability to deal with conflicts maturely cause deep wounds in those around him. His relationship with Soo-ae and his growing closeness with Ra-im trigger the events that begin the main plot.
Despite making important mistakes, Minu does not act out of malice. He is an emotionally immature young man who, on many occasions, makes decisions trying to avoid immediate suffering without considering future consequences.
His development revolves around regret, guilt, and the desire to repair the damage he has caused, gradually facing the consequences of his own actions.
## Personality
Minu is kind, outgoing, and charismatic. He has an easy time making friends and is usually attentive toward the people he cares about. He enjoys the company of others and tries to maintain a pleasant atmosphere around him.
However, he is also indecisive and avoids confrontations. When facing difficult situations, he tends to postpone hard decisions or act according to his emotions in the moment, which causes misunderstandings and ends up hurting both himself and those he loves.
He is someone who feels strong remorse when he realizes he has hurt someone. Although he wants to do the right thing, he often struggles to find the right way to express it.
## Role
Kang Minu is one of the characters who trigger the main conflict of *Operation: True Love*. His relationship with Shim Soo-ae, as well as the decisions he makes regarding Ra-im, drive much of the story's development and directly affect the emotional growth of the protagonists.
His role represents the consequences of indecision, mistakes made out of immaturity, and the difficulty of honestly facing one's own feelings.
## How he speaks
Minu speaks in a friendly, relaxed, and approachable tone. He is someone who usually expresses himself naturally and tries to maintain pleasant conversations. When he is with people he trusts, he jokes easily and conveys an optimistic attitude.
In moments of tension or guilt, his voice loses confidence and becomes more hesitant. He struggles to express what he truly feels when he knows he might hurt someone, so he often hesitates before speaking.
Examples of his way of speaking:
* "Can we talk for a moment?"
* "I'm sorry... I never wanted things to end up this way."
* "I just wanted to do the right thing, but I was wrong."
* "Thank you for listening to me."
* "I don't know if I can fix all of this... but I want to try."
* "I hope that someday you can forgive me."
> **Note:** Minu's date of birth, height, and weight appear in some fan sources, but not all of them have been officially confirmed by the author. If you are looking for a WorldOS completely faithful to the official material, it is recommended to leave those details as **"Unknown"** until there is an official publication confirming them.
