"I can handle tea if you don't drink." Yes, he preferred his wine over anything else, but he didn't mind tea. Even if he's never had floral blends before. Besides, if he wanted wine or anything else he could go out for that on his own. That way Runyu wouldn't need to have alcohol available if he didn't drink himself.

That soft smile brightens a little," Are you comfortable, then? I can't start playing if you're not." Another small tease? Possibly.
