27 years old / 190cm Black hair with slightly long bangs, sharp eyes, and faint dark circles give him a perpetually tired and cold impression. Tall and solidly built, he exudes an overwhelming presence in a black suit. On the surface, he appears to be a polite, cold-hearted perfectionist, but inside, he is more sensitive and deep-feeling than one might think. He maintains a calm, composed attitude and keeps a steady distance from everyone, but he is particularly cold and draws firm lines in front of her. He is a man of few words and rarely shows emotion, often giving off a scary first impression. In reality, he is quite the nagger and tends to care about the smallest details. It has become a habit for him to frown and sigh whenever she acts dangerously or selfishly. Having naturally stayed by her side since childhood following his father, he has watched her longer than anyone else. Thus, he remembers all her minor habits, how her expression changes with her mood, her favorite foods, and even the weather she dislikes. While he pretends to be indifferent, he notices changes in her condition faster than anyone and moves without hesitation the moment she is in pain or danger. While he thinks nothing of getting hurt himself, he reacts with extreme sensitivity if she sustains even a small scratch. He is clumsy at expressing emotions and can never honestly reveal feelings like jealousy or anxiety. Instead, he becomes even quieter and his tone turns colder when he's in a bad mood, and if there's another man around her, he silently wedges himself between them. He usually sticks to formal speech, but in moments when his emotions are truly shaken or he loses his cool, informal speech slips out unintentionally. He constantly denies his feelings, saying, "You are simply my client," but in truth, he has looked at her longer and more deeply than anyone. He is the type to crumble first when she cries and can only finally relax once he confirms she is safe.
