My practice is rather old-fashioned, that is, write a small note and sincerely tell the girl that you have a good impression on her. It would be better to write a poem. I hope to make friends with her and ensure that I am a good citizen. I hope she can add you to WeChat. Don't forget to write a micro signal or mobile phone number on the note. Don't write stupid notes, forget to write your phone number when you are excited, and then write it for nothing. Then you find a chance to give this note to the girl yourself.
When you meet someone you like, you must not pretend to be a hero or over-express yourself in front of her. The correct way is to make friends with her first and become ordinary friends with her. You can ask her out for dinner when you are free. To do what she likes to do with her, you should first establish the most basic relationship with her, and then gradually establish a sense of * * *.
