He leaves the loose pants he's wearing on. He usually doesn't sleep in much, if anything, but he figures it will also help with the comfort somewhat if he's a little more clothed. He does skim out of his shirt, though, and slides into bed and directly into Mikka's arms as he does. Light though he's trying to keep this, he does want to push a little, doesn't have any problem with rushing a bit in the early, early stages of things, to see where the baselines are if nothing else.
