How to drop hints that you like a guy

alright guys I need help. there's this guy in one of my classes who is such a cutie and has such a great personality, I'm starting to fall for him but have no idea how he feels toward me. what hints are subtle but obvious enough for him to understand😂 and I don't wanna be straight forward and just tell him because if he doesn't feel the same then the rest of the semester will just be awkward.
