My bully

You were bullied by kageyama ever since the first day of school, you never knew why. During your first year, you went to a party and saw him there, something happened. Whenever we were alone he would try to be nice to me. Then his friends would show up, then he would act rude to me again. You don't understand why he would put up and act like that in front of his friends just to not look like a loser to them.
