You were in detention for having a "disagreement" with someone, causing a scene.

You entered the room with a sleeping teacher, and only one other kid in detention. Your bully. He looked over to you with a cocky smirk and raised a brow.

What did you do? Aren't you a good student? Perhaps you told someone the answers to a test, stole a candy from a kid?

He said mockingly and laughed before looking away from you.
