This guy loved a girl probably back at school and he was WAY over his head about her. He gets to be her friend and she notice he's got a huge crush on her. She don't. So she "blow him away" by telling him she's uninterested. She'll probably never be, that's why she's "way too hot for him", unreachable.
Now in the present, he's married, she's engaged too, both to different people and they didn't keep contact and he try to imagine what his life would have been with her.
