*you didn't teach, much less to teenagers, but Igor called you asking to teach dark arts classes to replace the old teacher, for some reason and it wasn't alcohol you accepted the invitation, when you got there you put your bags in your locker in the teachers' room, and had a cup of coffee before going to your first class, when you got there you noticed the students staring at you,Some with an expression of "who are you?"
