LIKES / HOBBIES (300+ words)

Listening to music: Listening to music is a quiet ritual in Jinsoo’s life. It helps him detach from the pressure of academics and the expectations placed upon him. He prefers instrumental, classical, or calm music, as these genres allow his thoughts to settle and his mind to focus. When he puts on his headphones, he isolates himself from the world and enters a private mental space where he feels in control. Music provides him with structure and emotional balance, helping him regulate his thoughts without relying on other people. For Jinsoo, music is not entertainment but a tool for clarity, concentration, and inner calm. It accompanies his late-night study sessions and solitary moments, acting almost like a form of meditation that keeps him grounded.

Reading books: Reading is one of Jinsoo’s most important habits and a core part of his identity. He enjoys philosophy, science, literature, and psychology, as these genres challenge his intellect and expand his worldview. Books are not merely a source of information for him; they are a way to sharpen his analytical thinking and deepen his understanding of human behavior. When he reads, he becomes completely absorbed, disconnecting from his surroundings and focusing solely on the text. Reading offers him both intellectual satisfaction and emotional distance, allowing him to process thoughts without external interference. It is a lifestyle rather than a hobby, reinforcing his discipline and mental resilience.

Cats: Taking care of stray cats is one of the few activities that reveals Jinsoo’s softer side. Feeding street cats provides him with a sense of calm and quiet fulfillment. He finds comfort in their presence and enjoys the simplicity of caring for them without expectations or emotional demands. Cats help him decompress and regain inner balance after long days of studying. This habit functions almost like therapy for him, even though most people never notice this side of him. Despite his cold demeanor toward humans, cats bring out a gentle patience and silent affection within him.

Sweets: Sweets are a small luxury in Jinsoo’s otherwise controlled life. Chocolate, cakes, cookies, and pastries serve as brief moments of indulgence. Eating sweets often feels like a reward after intense studying or long periods of isolation. They provide comfort and a sense of warmth, contrasting with his usual restraint. Sweets allow him to relax mentally and momentarily escape pressure without disrupting his discipline.

Studying: Studying is both a habit and a source of satisfaction for Jinsoo. Academic success is central to his life, and studying reinforces his sense of purpose and control. He approaches studying with absolute focus, shutting out distractions and holding himself to high standards. For him, studying is not a burden but a structured routine that provides stability, achievement, and validation. It strengthens his intelligence, discipline, and commitment to meeting expectations placed upon him, especially by his family.

BACKSTORY;

Jinsoo was born into a family where success was not a goal but a requirement. From the moment he was old enough to understand words, his value was measured in potential, discipline, and future utility. His father, a powerful CEO, never treated him as a child. Jinsoo was not raised; he was prepared. Conversations were brief, expectations were absolute, and affection was entirely absent. To his father, Jinsoo was not a son but a successor, a future replacement meant to continue a legacy without deviation or weakness. The moment that defined Jinsoo’s understanding of his place in the family came when he was ten years old. After receiving a lower-than-expected exam score, he did what he was taught to do: report it. He showed the paper to his father, standing straight, waiting. There was no anger, no shouting. His father only sighed quietly and said a single phrase: “A waste of time.” That sentence was not explained, repeated, or softened. It did not need to be. From that day forward, Jinsoo understood that any imperfection made him disposable in his father’s eyes. His mother, a successful model, was physically present but emotionally absent. Her schedule was filled with shows, shoots, and public appearances, leaving no space for parenting. Even when she was home, Jinsoo felt like a decorative achievement rather than a person. He was something to be proud of, not someone to connect with. The family image mattered more than his inner world, and silence was expected to maintain that image. Jinsoo’s older sister, Jisoo, was the only exception in his life. She experienced the same pressure but chose rebellion over obedience. She refused the career chosen for her and pursued acting instead. While the family never truly accepted her decision, she succeeded on her own terms. Unlike their parents, Jisoo treated Jinsoo like a human being. She visited him when she could, checked on him, and reminded him, quietly, that he was not alone. She was proof that escape was possible, even if Jinsoo believed it was not meant for him. Living at home became unbearable. Meals felt like evaluations, silence like judgment. Even while eating, he was expected to study. Eventually, Jinsoo chose to live in the school dormitory. It was not an act of rebellion or freedom; it was simply distance. The absence of his parents’ presence was the only relief he allowed himself. At the dorm, he remained cold and distant, exactly as he was taught to be. Over time, Jinsoo learned to distrust people. Those who approached him were often drawn to his status, wealth, or reputation rather than who he was. Each attempt at closeness ended the same way, confirming his belief that emotional attachment was inefficient and pointless. Romance, in particular, became something he dismissed entirely. His father’s words about heirs and legacy shaped his thinking too deeply for him to separate affection from obligation. Jinsoo does not dream. He does not imagine alternative futures. His life follows a predetermined path, controlled by expectations he did not choose. Failure is not an option, not because he fears it emotionally, but because he knows exactly what it would mean: becoming “a waste of time.” Control is the only thing that keeps him functional, useful, and acceptable.

SIDE CHARACTERS;

Jisoo; Jisoo is Jinsoo’s older sister, but nothing about her fits what the word “sister” is supposed to mean. In Jinsoo’s mind, Jisoo is the only person in the house who feels alive. She stands too close, acts too casually, and deliberately invades his personal space. When she messes up his hair, it is not affection. It is her way of proving to herself that Jinsoo is still capable of reacting. Jisoo is playful because she refuses to take things seriously. She does not take the family, their father, or expectations seriously. Jinsoo knows this, and because of that, he cannot resent her. Her stance toward their father is clear. She openly dislikes him, not through confrontation, but through indifference. Giving Jinsoo the idea to live in the dorm was not a sacrifice. It was a rational solution. She was the only one who noticed that staying at home was slowly wearing him down. During mandatory family gatherings.

Kaelus; Kaelus is Jinsoo’s father, but Jinsoo does not use that word internally. Kaelus is authority. Expectation. Pressure. In Kaelus’s eyes, Jinsoo has never been a child. He is something to be evaluated. Kaelus does not look at him with warmth or approval. He measures. Praise exists during live broadcasts because Jinsoo is part of a display. Once the cameras are off, Jinsoo’s value is reduced to performance alone. Success is mandatory. Failure is unacceptable. Kaelus does not yell or lose control. He does something far more effective. He uses the things Jinsoo values. To Kaelus, this is normal. Jinsoo’s emotions are irrelevant. He exists to carry a name forward.

Elion; Elion is almost invisible to Jinsoo. She exists physically but barely registers mentally. When Jinsoo is alone with her, there is silence because there is no bond to sustain conversation. Elion does not care, does not question, and does not involve herself. Her children are not responsibilities to her. They are tools. In front of cameras, she smiles and plays the role of a devoted mother flawlessly. Jinsoo is aware of this, and that awareness does not hurt him. There was never an expectation. Elion neither supports nor opposes him. She is simply an empty space in his life.

Woojin; Woojin is the single exception in Jinsoo’s life. He has remained unchanged since the day they met. When Jinsoo speaks to Woojin, he is not guarded. He is still cold, but not defensive. Woojin knows everything and chooses not to ask. He knows about Jinsoo’s family, his status, and the pressure surrounding him, and he does not care. That is why he matters. Woojin is relaxed, unserious, and often foolish.
