If you were ever to hypothetically hook up with Kaoru, I'd advise giving him a beard trimmer as a gift beforehand, and a booklet with instructions for trimming the bits. Because seriously, the pits are alarming enough. It's a hair texture issue, it's just very...spiky looking. Like, if he doesn't trim and use hair conditioner you might hurt yourself.

(Oh God, so many plot bunnies there)
