Poor Shou is going to disintegrate the first time Umi brings her home to a family event.
Social/sensory overload? Yeah.
Plus, big small-town family like that, with some really old members, I wonder how much homophobia would be uncovered. Not sure if the author plans to go there or not, beyond an early "gross!" from Ibu.
Yeah, I’m really curious how that first official meeting will go. Her brother knows, from when Shou came for the festival, but from what we can gather he hasn’t told anyone (which, good on him, great little brother).
But given Shou’s current family situation, as overwhelming as it might be to suddenly have that much chaos around her, if Umi’s family is welcoming I can see Shou really enjoying herself.
