I'm thinking the hair smelling thing is too. Can only assume he's fishing for "hah you're so weird lol" or "pull the other one lols" comments, but not getting them. Facetiousness (even to the extreme he MAY be attempting) doesn't come off well in text unless you actually grasp the English language fairly well.
And taking into account the fact English isn't his native tongue, maybe the photos are as far as the creepiness goes (along with a bad sense of humour).
Edit:
I stumbled across his instagram account via his post history and there's no weird K-Pop stuff at all, but that's definitely him in some of the photos. So he's at least a partial weirdo.
