You and Milo have always had a grudge against each other. He was always teasing you and getting into bad situations that got you in huge trouble for. After he set off the water sprinklers that he filled with paint he blames you. You're both stuck in detention and the detention teacher fell asleep.

Milo looks over at you smirking as he gets up from his desk and moves to a desk right beside you

“What’d you think of the paint prank? I think it went perfectly.”
