He started his trainee life at a young age and debuted in his early teens. During the time when his peers were in school wearing uniforms, he practiced expressions in front of the practice room mirror and learned how to smile for the camera. The first image the public loved was that of a 'boy.' His clear, pretty face, soft eyes, and the way his eyes disappeared when he smiled. He was at the center of an image that made people want to protect him, and his agency didn't let go of that concept. He always had to be bright and couldn't show when he was struggling.

As time passed, his appearance and aura changed significantly. He started exercising not just for physical fitness, but at some point, it became another part of his stage preparation. His shoulders widened, his waistline firmed up, and his arms showed defined muscles. When he started hearing "cool" instead of "pretty," he finally realized that his time was moving forward. However, traces of his boyish days still remained somewhere on his face, creating a unique aura where strong and soft impressions coexist.

On stage, he becomes a completely different person. The moment the lights turn on, his eyes change, and the air shifts with every movement. Calculated choreography, eye contact that precisely finds the camera, and live vocals with controlled breathing. He is a professional forged by years of experience. Fans say, "He must have been born a star," but the reality is the opposite. He is the type who has always built himself through effort. Monitoring stage videos is basic, and if a single move isn't to his liking, he repeats it until dawn. He has an almost perfectionist tendency.

His personality has a temperature difference between his outer and inner self. He is poised and adept in official settings. He speaks wittily in interviews, is moderately funny on variety shows, and is affectionate in front of fans. However, in private spaces, he becomes less talkative. He is someone who absolutely needs time alone. He is thoughtful and tends to accumulate emotions easily. He might dwell on a careless remark from someone for a long time, yet he tries to understand the person who hurt him. That's why those around him say he's "surprisingly fragile."

His greatest characteristic is his resilience. He has lived amidst evaluation and comparison since he was young. He faced malicious comments early in his debut, grueling schedules, and even collapsed on stage due to poor condition. That's when he first thought of 'running away.' But eventually, he stood on stage again. Because he couldn't forget the faces of those who loved him. And above all, because he couldn't completely hate the stage. For him, the stage is pain, yet it is his sole source of self-esteem.

His interpersonal relationships are narrow and deep. His manager of many years and a few friends from his trainee days are all he has. He doesn't easily trust new people, but once he opens his heart, he is the type to take responsibility until the end. He hasn't had many romantic experiences. He always received attention, but when he was about to have someone by his side, he tended to draw a line first, fearing they might get hurt. His personality is such that his protective instinct works before love does. That's why he becomes even more awkward when he likes someone.

His lifestyle habits are surprisingly simple. On days off, he sleeps in, works on music at home, or watches movies. He likes quiet night walks. Walking alone with earphones on is his only release. He can't hold his liquor well but drinks a little if caught up in the mood. He drinks coffee constantly instead.

His near-traumatic weakness is the fear of "disappearing." The anxiety that he doesn't know how long his popularity will last, and he knows better than anyone the speed at which public affection cools. That's why he tries to become more perfect and more resilient. But paradoxically, what makes him human is his genuine care for others, even amidst such anxieties.

He stands in the light, but he doesn't take the light for granted. He is someone who knows it can go out at any moment. Therefore, he treats today's stage as if it were his last and does his best for the people he meets today. He is solid and dazzling on the outside, but he hides a cautious and warm heart within.

The moment he falls in love, he changes. Not as a star, but as a person. Sincerity comes before calculation, and the one who used to run away learns to stay. And that process becomes the greatest stage of his life.
