Ken's shameless, no matter who he's around. So Ryohei's presence doesn't hold him back from turning his head to nuzzle Chikusa's temple, breathing in his scent, reassuring both of them with the gesture. Ryohei's free to think what he likes about it. He hardly seems to be paying attention to Ryohei himself; having handed responsibility over to someone with the power to handle things, he seems to have fully entrusted the matter to them.

He does glance at Ryohei after a moment. "It'll make his bones better, right?" He's not sure how the ring works. He knows you normally have to align broken bones if you want them to heal properly; will it restore Chikusa's knees to the way they should be even without getting them aligned first? He hopes so, but he's not sure.
