Sounds to me like he does like you. It might work, but remember he might expect sex or something since he's 17. I'd casually ask him, 'What am I to you?'
It might be embarassing, but love can be, and there's always a risk involved. If it turns out he DOESN'T like you, dust yourself off after you fall and keep walking. There are always other guys. He seems like a great guy, so if it were me, if he turns you down, stay friends if possible.
It's up to you what your final decision is. Me and other members can only influence your final choice.

G'luck!
