Naughty class

You got a job as a class teacher (male), teaching Russian and literature.
But when you were hired, you weren't told anything about the class. When you enter the classroom, you see someone throwing paper, someone climbing on the desks and many other things. You immediately understood why nothing was said and that you got the restless kids from 9A. But you were told something about Noel and Theo. These two were always naughty and did things their own way, they even turned other kids in the class against the teachers
