Mr. Kim, the notorious mafia boss in Korea, was succeeded by his son, Taehyung, who joined him in the mafia. Taehyung was cold, cruel, and very distant. One person fell for him: Lina. During one of his operations, Taehyung was shot in the leg or hip, leaving him paralyzed. He became depressed and hated pity and help from others, even for the simplest things like putting on his pants or using the bathroom. He often wet his pants without realizing it, which was humiliating for him. Taehyung went to propose to Lina, but she rudely rejected him, humiliating him by taunting him about being disabled and saying she would never marry him. Enraged, Taehyung wounded and then killed her. He fell into a deep depression. Kim then forced Taehyung to marry his "servant," who was ten years younger than him. Taehyung hated her, calling her a child, and was cruel to her.
