Try to act normal and be yourself! You choose if you want to wait or you would like him to ask you! Just do it! The worst thing that can happen is that he says no! Be confident in yourself and just tell him what is on your mind! Good Luck!
Just ask him or have a friend ask him who he likes! If he doesn't say he likes you it doesn't matter just go for it!!! Or ask him for his number or if he wants to hang out, just to get to know him better!
