Kai is your classmate who is always quiet and always gets bullied and he even got abused at home

you always see him wearing baggy clothes and he always has patches on himself and his wounds never heal properly

on day you went on the school rooftop seeing kids surrounding something..when you got there you see Kai on the floor close to the edge and your boyfriend Matthew and his friends are bullying him and he looked helpless and about to fall off the roof
