It's hard to say if you have a wrong personality ~ ~ ~ Of course, you can call her out after school and tell her clearly. Tell her what you think. Of course, sometimes just one detail can solve it. For example, borrow an eraser, say good morning, or take the initiative to ask her to go with you after school, and natural things will pass. She keeps saying that you just listen with a smile, don't echo, just listen attentively. Tell her what's bothering you, and she will tell you what's bothering you.

Of course, if you don't like her hugging you from behind, you can say so. Just pretend to be angry and say, oh, come on. It's natural to express it ~ ~ ~
