Looking back, is it a joke or a joke?

Probably, but if you just take the initiative to tell jokes and have a brain teaser, it will be difficult to prove it. See if he is nervous when he sees you.

Blushing? Are there many small moves? Ask his friend if he has changed a lot recently. Do you pay more attention to one aspect than before? Will he be incoherent if you take the initiative to talk to him? You look him in the eye and stare at him to see if he is avoiding your eyes.

If he is a student, he will start to pay attention to you and want to get your attention. You can try him.

However, other situations are not excluded.

This is your own life, but only by making your own decisions will you not be influenced by fate and others.

The decision is in your hands.
