What can I do to make him understand?
Maybe your attitude towards boys is ambiguous. Hehe, reflect on yourself. If you really think there is nothing out of line, it is that your classmates are so annoying. If that's the case, you can just tell that boy to stop pestering me. I'm not interested in you at all. Don't misunderstand me. I'm nervous about studying now, so I don't have time to concentrate on you and your girlfriend. I have no experience to share with you. Don't always show me your note in the future. Let him solve any problems by himself. If you can't tell him in person, write to him or chat with him on QQ. What did you say?/Sorry? I wish you get rid of your troubles as soon as possible
