yuna is so used to being confined to her house that she'd be happy with any kind of date that's not stay-at-home! she has expensive tastes because that's what she's used to, but i imagine she'd prefer more hands-on dates... which madara is happy to give!
they'll go to flea markets together, or art galleries—things that accommodate both of their tastes. yuna especially loves going to markets because she's not only fond of people watching, but she gets to listen to madara ramble about the origins of items for sale; his knowledge of rare things exuding. they ALWAYS hold hands and yuna gets pouty if he isn't doing that (which is rare even for him lol)!
