Jade kisses back, chuckling quietly. "I am an old man."

But he's perfectly fine now. The mental strain is gone, locked away completely, and he has a new mystery to preoccupy himself with. Right now, Jade is more preoccupied with the sensation of having somebody else on top of him. He had expected Shinjirou to sputter and pull away, but perhaps his desire for contact trumps the oddness of the situation.

It's unexpected, but not...unpleasant. Jade doesn't entirely dislike it, at least, which is more than he had expected.

"But it's terribly sweet of you to worry. Thank you." He may look and sound perfectly polite, but his insincerity can be felt all the same.
