Random guy at school looks at me in the halls?

I always find myself catching this guy looking at me in the halls at school, but he always looks serious when he looks at me and I seen him with a girl I think might be his girlfriend, I don’t know if he is judging me when he looks at me or maybe knows something about me or maybe finds me attractive? But I never have met him before.
