Why would a guy try to get my attention? He walks pass me several times when I’m talking to someone or hovers near me?

He does this regularly, but doesn’t approach. It’s like when I’m talking to someone, he’ll come and walk pass multiple times. He is cute so I don’t mind, but it just seems odd, because no other guys do that,
