Invite a quiet girl to dinner. If he doesn't come out, shall I go directly downstairs?

A little abrupt. After all, you've only been friends for five days and you don't know each other yet. You also said that she is a very quiet girl. I think the family must be strict, and she should be cautious and considerate. Maybe she is not the kind of person who is good at expressing. You can ask her what kind of boy she likes on the phone, and then ask her what she thinks of you these days. This kind of thing can't be urgent. I had a friend, but it didn't work out in the end. Another point is that you call for a long time and many times, which means that she doesn't hate you. On the contrary, she may have feelings for you, just because of face or family factors. Give the other person time to get to know each other and let her accept you slowly. A watched pot never boils. As for you, there is a girl who wants to introduce her brother. If you know this girl, you can tell her that you like her and tell her not to introduce her. Besides, you should have confidence in yourself. Since you intend to make the person you like happy all your life, don't question your love for her. Come on! !
