If you want to test whether a person likes you, you send him a message saying, "xx, I have a crush on someone." If the other person has a crush on you, how will he respond?

This kind of test scores people according to what kind of personality they are talking about. If they care about face, they will probably say congratulations and choose not to contact you again. Of course, some people may not give up or have high emotional intelligence. Seeing that you are talking about him, they will take this opportunity to confess to you, thus achieving a marriage.
