Wow, I do agree, NatsuNao is cannon. Actually, it does remind me Touya x Yukito from Cardcaptor Sakura. How do you think they spend a typical Sunday?
I’ve never heard of Cardcaptor Sakura but now I’m intrigued.
I think Natsuya and Nao would probably spend the day at home together. Nao would get up early like he normally does, but Natsuya, still half asleep, would pull him back into bed because they don’t have anywhere to be that day so you are not getting up at 6am. Eventually they would get up, and Nao would make something nice for breakfast because Natsuya can’t cook without setting the kitchen on fire. After a while in the house, if the weather is nice, Natsuya would probably suggest they go somewhere, not telling Nao where that is. He would agree, of course, and figure out where they were headed, of course, when Natsuya’s taking a bag with him for some reason. They’d end up at a pool because where else, and spend most of the afternoon there. When they head home, maybe Nao cooks dinner, or they order something. They’re ready for the next week of needing to go places and do things, so they can spend the evening sitting together on the couch and talking until it’s time to go to bed.
