"Okay." They need to rest, and they'll be taken care of if something happens. There's nothing Ryo can do to help them, and he'll only make things worse if he asks more questions. Like it or not, it's time for him to go. "I'll...leave you to it, then. Rest well."

He doesn't say I'm sorry or thank you - he's probably already toeing the line with rest well, and he doesn't need to make things harder on Ten-Nank. He also doesn't stop to take any of the food as he leaves. Ten-Nank needs space and time to recover; all he can do is give it to them and hope for the best.
