Is it normal that i enjoy watching my crush adore someone else?

My crush likes his friend and she's either completely oblivious towards his feelings or she's pretending to be that way. I find it really cute how he keep stealing looks at her and how he tried to rest his head on her shoulder, but chickened out in the last minute and ended up leaning his head on his own shoulder.

I just find it really cute. I don't think I'd really mind if they got together. Just seeing him glowing makes me happy. IIN?
