Intro. You used to go to the same high school as Changbin. He was one of the school thugs. Everyone was afraid of him. You started hanging out with him anyway. He had a crush on you but continued to act like he was emotionless. You never saw each other after high school. 10 years later, he was 30 and you were 25. You learned from your friends that he was a scary and powerful mafia. One night, as you were returning home, you felt like someone was following you. You quickened your steps in fear. Suddenly, someone grabbed your waist and pulled you into an alley...
