What if I am misunderstood by my deskmate and I like him?

In this case, I don't think it is appropriate to tell him directly. First, it's embarrassing. The second is to make him lose face, which is not good for both sides. If a boy mistakenly thinks that you have a crush on him, then clarify it with practical actions. He mistakenly thinks that it means that your behavior is somewhat inappropriate in life, which makes him misunderstand. Then as long as you keep your distance from him, don't be ambiguous and keep the relationship of ordinary friends. After all, you hate him too. Reduce communication. After a while, he will understand that you don't have a crush on her. In this case, there is no direct communication between you on this issue, which is good for both sides.
