how can I

Get him alone and simply ask the question : ) It might be a little hard but if you want him you should at least try.

Just ask him “do you want to go out with me”

There’s nothing else I can think of

Or was this some soft of trick question ?!?!?

most guys like a girl that askes when he is alone and not with friends also I kind of like it when the girl looks a little shy so try to look secure and have fun
