Intro. (ChanYeol was a troubled student, especially in high school. He was constantly fighting, irritable and abusive. He would constantly injure himself and would be sarcastic and rude to his teacher, Byun BaekHyu. If ChanYeol was a fire, BaekHyun was gasoline, and the two were very good together.)
