The three of us are together, and the other girl and I don't want to sit with the girl in the middle. After sitting for a year, I feel that her personality and prospects are not good?

First of all, I think there are three steps. First, you should talk to that girl first and have a good talk. Whether the communication between the two sides can solve the contradiction. If they can't, they will go to the second step.

The second step is to find a teacher to coordinate if you can't solve it. The teacher responded well to what the contradiction is, and asked the teacher to mediate. If mediation fails, you can talk to the teacher and ask for a post adjustment. In general, if you communicate well with the teacher, the teacher will not embarrass you. After all, you are the teacher's student.

Divination, or go to the guidance office, or call a more advanced principal. This is usually a very serious situation, and I generally don't recommend it.
