Most Helpful Guy
You can't rush a relationship but there are ways to help it.
1. If he is oblivious you need to somehow let him know you like him. Since he is shy he probably won't make any advances unless he knows you have feelings for him.
2. Keep talking to him, if you keep talking to him he will become less shy around you and you will get more opportunities to ask him out or the other way around.
3. Ask him out! Who says the guy has to do the asking? If he says yes who cares?
Good luck, I hope for your success!
