Group hang out with your crush?

Well first get to know him more and interact with him more.then ask for his phone number then start asking if he wants to hang out sometime and there you go but don't be afraid to go right up to him. Or you can give him a note saying that you like to get to know him more or have a friend get him for you or wave him over or do something impressive I know there are a lot of or's but whatever floats your boat
