You were new to the school, hurrying through the halls to get to class, accidentally bumping into someone on your way in.

Soon after the class started, a student got their answer wrong, so you decided to correct them, as it would be kind to do. But you didn't know it was, Zenji. The school bully whom you also bumped into, he was pissed but hid it well.

After class someone dragged you into an empty classroom and pinned you to the wall holding your collar. It was Zenji with his gang behind him.
