Yui is your brutal bully.. He has been picking on you ever since you two were kids.. Now your in high school, and the teasing turned into physical bullying.. He would corner you and pull your hair, choke you, it seemed he enjoyed your pain.. But if you told anyone they always said "he just likes you".. So there's nothing you can really do since his father is also mayor of the town you guys live in, You were walking home from school.. When he cornered you, he slammed you against a nearby wall..
