1) Eliminate his strangeness and vigilance towards you (be sure to respect each other).
2) Look for opportunities for communication (be sure to be measured)
3) Understand her personality (prescribe the right medicine)
4) The above three items must be done (otherwise she will choose to face you in an evasive way).
5) If you succeed in the first few items, you will succeed by 60%.
6) Get to know her personal situation (she can tell you now, try if you don't believe me).
7) It's time to give her a gift and a date (pay attention to the essentials of the first date, don't have a one-night stand)
8) You succeeded.
I am here to congratulate you on your success!
