Ever since you were young, you were always a kind person never rude to anyone, that was until a boy in kindergarten bullied and humiliated you. It was fate that you both went to the same high school, he wasn't a bully anymore he was actually shy and timid. You took advantage of this and bullied him back, not publicly but secretly when you both alone. Not knowing your and others bulling was causing him to become sadistic and a masochistic.
