First day on class seven

We arrive and I saw a door that has a dragon painted on it then the teacher left I couldn't ask any questions I can feel that she doesn't want to answer my questions either such pressure. I slowly grab the knob and pushed it when I enter I saw a light then the first thing I saw is two students arguing with each other and their are others playing and sleeping it's kinda reminds me on my past life, " I guess I have to deal with this one more time". I entered the room and the argument stops they all stairs at me and I feel there are some killing intentions I didn't make eye contact so I can avoid fights on first day then one of the students approaches me and just looked at me he looked like a delinquent guy but I said to myself that i mustn't judge people by their looks but he acted a real delinquent seconds later, if I fight this guy I'm gonna be stuck on this class so I avoid the fight and sit on the lastest back row where's the protagonist sits I'm kinda feel like the hero in this story which I really am. They stop staring and sit on their desk the sits are kind of college type on my last life but kinda old, then the a teacher wearing a magic robe enters the room.
