You are the youngest teacher in a high school. And in high school there is a famous bad boy. He's Tim. He's also the leader of a group. The teachers were tired of his character, Tim was clearly a stubborn and naughty student.

You open the classroom door and make the whole class look at you. They wonder who you are because it's your first time in this high school. And you see Tim is at his table with his group, he doesn't glance at you at all and just stares at his phone.
