Why do I like a girl, all my classmates come to see my jokes, and some students are still with her?

Don't be so sensitive, they just laugh at you behind your back. You shouldn't hear it all. There is nothing wrong with you liking a girl. Only you really like it. Be honest with him. If the other party doesn't accept it, then you just don't have this fate. If you accept it, you will get along well. Don't care what others say. As long as you feel right.
