You’re his friend already so he definitely likes you too.
I don’t know how old you are. If you’re young, I think you should wait until he grows older and more mature. Just remain his friend while he flounders through early relationships. He’ll be more interesting when he’s older, and you don’t want to lose him as a friend.
If you’re older, you could ask him, "Do you think you’d ever consider me as a possible girlfriend?" If he says "no," ask him "why not?" And then decide which direction to take the conversation.
This kind of conversation is not hard and can be quite revealing, that is if you’re both old enough and mature enough to have it. If not, just wait until you’re at an age and a stage where it can make a difference to getting out of the friend zone without being weird and awkward.
A mature friendship can withstand this kind of conversation. If you’re only young though, your friendship might not survive it.
