Nothing, but the other person is very reserved and doesn't want to be accosted by you. Maybe she thinks too much, hahaha.

You're not the only one in this situation. There should be many. It is a good thing for girls to be vigilant, which will reduce many misunderstandings and troubles.

Love at first sight is an ideal state, and understanding after love at first sight is very painful. Romance is what everyone wants, but it is fate after all. I still prefer to have a long relationship, so that both sides will be calm and comfortable.
