I like a girl very much. I met her on a trip. Later, I asked for her QQ through a friend, chatted for a while, and then met her.

I suggest you take your time. If you have perseverance, just say a few words every day. She will get used to it after a long time. She will think of you gradually when you don't say hello. If you don't have perseverance, you can express yourself directly. If she refuses, you can forget it slowly. If you can't forget, you will have perseverance. Without a heart of stone, you will be moved slowly. It depends on your perseverance.
