If you can, don't choose that kind of teacher-student relationship. There are not many explanations, and students are not so good. If it's not good, it has a lot to do with looking up, or it's better to keep it as simple as possible.
People who are far away from pv tendencies, this is actually the most terrible, because many people, who are A, have no concept, but there are many such tendencies. They always raise their status, say how popular they are, and then talk to you about things you don't know, and they will keep hitting you, how stupid you are, how fat you are, and who wants you except me. It makes you feel bad. In this relationship, you admire him, and then you are more worried that you will be dumped. You really can't find anyone who loves you except him.
Such people are extremely selfish. In the name of loving you, they are insecure, keeping you away from boys and socializing. Actually, it's to control you. You can only have him in your life. Don't think about how I made such a mistake with low IQ. Then look at the fact that a girl from Peking University found an A boyfriend who committed suicide, and then talk to me. Remember, the right person must make you feel like a spring breeze and make you more confident to face life and study. Let you become more and more excellent and more self-motivated.
