Crushes

There was this guy last school year who liked me I did nothing about it. But secretly I liked him back and we sometimes talked. The new school year just started and I still like him. We have one class together and we see each other in the hallway but we don’t talk :( I wanna start talking to him but I don’t wanna make things awkward. I don’t know what to do. I don’t think he still likes me. I mean I never gave him a reason to :(

Some advice would be nice
