How would LES T behave when he has a crush on a girl?

You will look at her from time to time, but you are afraid that others will find out. If she takes the initiative to talk to you, you will be very happy and feel sweet in your heart. If you log in to QQ, you will want to chat with her, but click I'm afraid again when I come out. I always say some boring words and don't dare to express my thoughts. I always think of her suddenly at some point, but I feel terribly uncomfortable... If I was like this, I might always run away. He goes to chat with her and loves to tease her. The more angry she is, the happier he will be because he feels that he has attracted her attention...
