Why is he not accepting my follow request?

I have a crush on this guy who I see about twice a week because we go to the same drama class. We talk and laugh together and often catch each other looking. He always hugs me goodbye and sometimes brushes against me. We also hold eye contact longer than I would say I do with others. It’s still at a point tho where I’m questioning if he’s interested or not. I sent him a follow request two days ago which he hasn’t accepted or rejected and it’s kinda driving me crazy. Why has he not accepted it?
