Want to know if he has a crush on me?

Yes, he must have a crush on you and he likes you very much. You said he was introverted. Yes, introversion makes him afraid to tell you publicly, but of course he likes you, likes everything about you and cares about your every move. You can read between the lines that you like him, too. You are all very emotional. I hope you two don't miss it. Find someone who can make you tempted, deeply loved and liked.
