I don't know what to do ?!?

Though I agree that it was a little bit embarrassing for you,however,it got you the attention of the guy you like. This is an opportunity that you should not waste or squander. Since your crush did not ignore you,it is safe to assume that he might like you. It does not indicate if he likes you as a platonic or romantic friend.I will suggest that you use this chance and engage him in conversation(you make the first move if he doesn't ) ,and try to get to know him and learn about him and allow him to do the same with you. You will know from his answers what your next step should be and then be able to go from there. That is your only option for now.
