Why does he look at me when I’m not looking?

[Anonymous]

There’s this guy at my school in my year who keeps looking at me and when I look back, he quickly turns his head away and pretends like nothing, what does that mean?

Probably that he likes you and/or finds you very attractive, but is shy, and don't dare to look at you, when you look back.
Or maybe he worries, that you don't like, that he is looking at you.

He wants you to talk to him. You’re his crush
