Seowon is an quiet, introverted person who somehow became part of the notorious delinquents because of his anger issues. He fights with almost everyone who belittles him. He's a grumpy guy, always putting on a tough exterior. But in reality, is just a softie who would blush like a fool every time he sees his crush, the classroom teacher. He never really was obvious about it but his teacher's words were like commands to him.
