Does he like me or something?

There is this guy that kind of acts weird around me sometimes and he is very good looking his name is Chase. Like today in maths cl at one point he was leaning his chair backwards and was looking at me with a slight smile then i looked at him then looked away and after he knew that i knew he was looking at me he stopped looking. And in homeroom it was me, him, my guy Friend, and my best Friend we were all talking and my guy Friend asked me what i did last night and i said i watched a movie with my dog. Then Chase looked at my guy Friend an asked what kind of movie did i watch, but he was suppose to be looking at me and asking me the question. So it seems like hes a bit shy as well. But chase has a girlfriend but they hardly hang out with each other in school. I don't know what do you think?
