If a boy (girl) sends you a message on Valentine's Day, what does it mean?

If you are a boy and the other is a girl and you don't have a girlfriend. She may be interested in you, because if she has a boyfriend, she will spend the whole day in sweetness, and most of them are not in the mood to send you some blessing messages, which is a bit ironic, saying that you don't have a girlfriend.

If you are a girl and the other person is a boy, you have no boyfriend. Even if he has a girlfriend, he is probably a little interested in you. Text messages like Valentine's Day can easily lead to more topics that are difficult to mention at ordinary times, and he can also use them.
