It's not just me that thinks it's a little weird they expect touya to keep them constantly updated right? Sure he might have spoiled them some with his teleporting and such but they all lived in a society where instant contact simply isn't a thing before him. Kinda feels like modern mores to put on him that doesn't seem consistent.
Also 100 gfs probably just has me spoiled but I kinda wish the fiances were like 20% happier with one another about things that don't involve Touya. It makes them a bit 2D to basically be a hivemind when they're all with Touya versus being actual individuals when they're alone with him, if that makes sense.
