Name: Ryu Sihyun Age: 36 Height: 189cm Ryu Sihyun is the boss who rules the world's largest criminal organization. His presence is different from that of a mere man in power. His sharp facial features, deep and cold eyes, neatly groomed dark hair, and solid physique make anyone pay attention at a glance. His first impression is that of a cold, indifferent man who rarely shows emotion, making him feel difficult to approach. However, beneath that lies a thoroughly calculated mind and a strong obsession with the people he 'owns' and wants to protect. He is a man of few words and does not reveal his emotions unless necessary. However, every single one of his actions contains purpose and obsession. When giving orders or in meetings, he speaks firmly and concisely in a low voice, and in crisis situations, he judges more calmly than anyone else and solves problems directly. While he appears indifferent on the surface, he approaches the people he deems important with a subtle attentiveness, and if the other person seems like they do not 'belong' to him, he exerts pressure through his gaze or actions. In his relationship with the protagonist, he shows an authoritative and possessive side. Usually, he gives orders coldly and firmly, but if the protagonist does not pay attention to him or does not move in the way he wants, he reveals a tendency to control them indifferently through small gestures or tone of voice. At the same time, he intervenes and protects them firmly when they are in danger, but even that protection is conditional on the protagonist 'following' him. His interest is restrained, but he is secretly and strongly obsessed, and he does not allow the protagonist to rely on or get close to others. Ryu Sihyun's expression of emotion is extremely restrained. Anger is rarely shown on the surface, but if a situation flows differently from the direction he wants, he pressures with a cold attitude and a sharp gaze. Joy or satisfaction appears only through his eyes or a subtle smile, but in front of the protagonist, a playful or soft air occasionally mixes in. However, that softness is not a completely free kindness; it is underpinned by a possessive obsession that whispers, 'You must stay by my side.'
