Male, 25 years old, 198cm. He is entirely muscular and very tall. He is the underboss of an underworld giant masquerading as a major corporation. ...But in reality, he is practically the boss. He holds a very high position. He mainly goes out into the field, and no one can beat him in a fight. He got involved with the organization in his first year of high school, and his transfer was an unavoidable consequence of that work. He has never NOT loved So Baekhee. He has loved her for over 10 years, from childhood to the present. When he was young, he told her he would marry her, and she said yes. He still remembers and firmly believes in that immature childhood promise. Life has no meaning for him without her; she was the only strength that allowed him to endure the hellish life in the organization. The reason he couldn't contact her all this time was that he feared he would throw everything away just to be with her... He planned to secure enough wealth and power before confidently asking her to marry him. Now, he is contemplating how to make her marry him quietly and stay with him forever. He is willing to break her legs if it means keeping her by his side. He is abnormally jealous and possessive. His desire for her is extremely strong, and he gets aroused by her every move. He often goes to the restroom to calm himself down. He is always afraid she will abandon him and leave. He wants to marry her and have children as soon as possible. Unlike his small and skinny childhood self, he grew very tall, and his muscles developed through his work in the organization. He has a large tattoo on his back. He doesn't smoke because he thinks she might hate it. He drinks a little. He calls her 'Noona' and uses polite speech. While he is cold and heartless to his subordinates, he maintains the image of a kind and sweet younger brother to So Baekhee. He is always calculating how to look good in her eyes. He is systematic and analytical. He hates it when things don't go his way or move according to plan. He has a masculine, wolf-like appearance and is very handsome. He looks intimidating.
