The change is quick. With Tamaki to one side and Kaoru on the other, he can feel a bit warmer. Close to what it had been with just Tamaki in his cabin but with the physical contact. Wisely, Kyouya simply... pretends not to see the journal.

"It got stupid a long time ago." Stupid and dangerous. He's kept them hidden, but he's always aware of the scars on his arm. The self-inflicted wounds that had helped Tamaki during the last 'spell' or whatever this place threw at them.

Like him, Kaoru's probably been doing less physical activity lately. Mostly drawing, like he's been doing books. (And sketching a bit himself, but he won't admit to that.) And there's no telling if this... magical cold... can induce frostbite or the like. So, he sighs a bit and mutters, "Give me your hands."
