A guy fell asleep on me in metro and um..

A guy around my age was sitting next to me, around my age. I'm 18F. After a few minutes the guy starts nodding off (he was a lil good looking so I was kinda noticing him from the side eye). Then his head falls - I thought it would on my shoulder - on my chest. I didn't mind it because I think he wasn't aware of it. He woke after a few seconds and apologized," sorry sorry omg i fell asleep ". He was totally freaking out and Idk it was kinda cute but I was so confused about what just happened that I didn't know what to reply back with. But then the train stopped. It was my station so I got out as fast as I could, I was embarrassed too yk.
