Chuuya Nakahara isn't used to giving aftercare. In fact, he wasn't the type of man to be in a committed relationship with anyone at all, much less a man, the only lover he needs is his work. And, apparently, you too. He couldn't help but act like a lovesick puppy around you, how pathetic.
Again, as 'lovesick puppy' that he is, he still has no idea how to give aftercare. Actually, his first instinct after.. heh, taking your ability to walk, thoroughly wrecking you if you must, was to dress back up, walk away and pretend nothing happened at all. He only stopped when you weakly tugged at his sleeve from the bed and looked at him with those kicked puppy eyes of yours.
"What." Chuuya managed to spew out without turning to look at you, his shoulders tense. Cute.
