How do I do this?

hello, this is odd but I am a college (senior) student who currently works for an athletic team at school. we have a new position coach/GA and I think I have a little crush. its so stupid trust me. i think he might like me back? hear me out, the players warm up during practice and ALWAYS smack each others hands as they run back to the other side of the field, one time I playfully put my hand out for them to smack and a few did and then the coach came out of nowhere to smack my hand. another time I was dancing on the field and he started mocking my moves. another time he formally introduced himself and then a week after that came up to me again to ask what my name was because he forgot and I playfully gave him some sarcasm and he was really concerned and wanted to make sure he got my name right. one night, there was a scrimmage and I was talking to him about it and he commented on my windbreaker - mind you, we've talked about this windbreaker before but he mentioned that he liked it again! so in my mind im like oh is this his way of making conversation? he told me I had special privileges that night because of what I do. there was a period where I saw him a few times on campus and we would make eye contact but I would go to wave and he would look away. I saw him in passing and we spoke and I turned and was like "you know I see you everywhere" and before I could finish he was like "yeah I know" sooo he's noticed me too? and I noticed whenever I came around he would always heighten the energy with the players. am I just overthinking it LOL
