Korean guy likes me more than a friend?

Love is the universal language, I'd say give it a chance. Maybe go out with him a few more dates before you make any moves. He may also be afraid to seem aggressive, so give him many oppertunities to make a move. Rub your own neck next time and tell him you didn't sleep well. Mention that you wish you could get a mage. See if he offers to give you one.
