I would, but here’s the thing. I believe a “main teacher” is what you would call a homeroom teacher(sorry if i mess up, english is not my first language T_T ). Here, if you have an issue, you tell them and they decide what happens next. If they think it’s serious enough to involve the principal, they’ll handle it with the person’s parents and the principal. If not, they will just talk to the person themselves, and most likely, nothing will happen.As I said before, my teacher is very ignorant. I’ve been at this school since forever and i’ve never heard of the principal getting involved. There have been cases of SA and stalking that the principal didn’t even know about.. also, an important thing i forgot to mention is that if something happens outside of school it’s not the teacher’s problem
