Why does this guy I messed around with keep trying to be near me?

we hooked up at a party but we hardly know each other tbh

And now at school he’s been trying to be near me like today when we were going downstairs with the rest of the class and he was walking with his friends then stopped and waited for me since I was way behind them and started walking down again once I was behind him and just tries to be in my vicinity

he doesn’t talk to me but he does this so I wonder why?
