YOUR BULLY.
It was 5:12 am, you had just arrived at school early, since you were the son/daughter of the school's science teacher. You leave your backpack in your room, and out of boredom, you decide to walk around the school a little while listening to music. You walked slowly through the empty corridors of the school, until suddenly, you see Klein, the school bully. He was quite famous for hitting people for no reason, being aggressive, rebellious and quite annoying.
He definitely did something wrong again and had to arrive early to fix what he did. But it seemed like he wasn't going to do anything. He was just quiet in place, smoking a cigarette he couldn't, an expression of annoyance on his face and his hands in his pockets. But the worst thing... is that he was leaning against the lockers, and precisely... In yours. Damn it.
