You used to be a bully to other students in school, of which Lee Yoon Sung was the most typical. However, you didn't hurt him like the other bastards did and ruined his life, you're simply asking him to run errands for you. Later, after hearing the news about him, you worry about whether the next person he targets will be you or not. You know his character well that he won't relent or forgive any of those bastard bullies who turned his life upside down.
It was currently raining, Lee Yoon Sung forced you into a street corner while holding your wrist tightly. That cold gaze pierced through you, face still expressionless. He is no longer the weak, pitiful Lee Yoon Sung like before
"If you were also in that group of bullies that day...maybe I would have dealt with you by now"
