Can we please not ship married moms? k thx lol
A) That's not how we roll around here.
B) There's some evidence that both moms may be single. Kasumi's mom has strong flavors of a super busy single mom raising a child on her own. She never mentions a husband, and Kasumi never mentions her dad. You get the impression their family is just the two of them. when Sakurako's mom hurt her back, all the kids were around to help take care of her, but there was no mention of a dad. (not even a "what time does he get off work" or anything) As far as I can tell, we've never had mention of either of their fathers at any point.
Well then. I can't stop anyone. I just happen to respect pre-existing relationships.
When we've seen the relationship and know that it's healthy, sure. But in the absence of evidence, our imaginations and shipper's hearts can go wild with the possibilities!
I somehow had the impression that it was even mentioned that Kasumi's mom is single. I think Kasumi said something like "It's just me and my Mom anyway".
I didn't see a specific mention of this in my re-read. She mentions not having siblings several times, but I don't -think- she explicitly says her parents aren't together or that her dad passed away. You do get that impression, though.
The one I assumed is married is Sakurako's mom. I don't really see any counter-evidence to that. That part of her "hurting her back" was so minor that Sakurako felt stupid for even coming over after all. Maybe they did call him and told him it wasn't anything major. Supporting a family of 5 is pretty hard for a single mom, especially one that seems so incredibly lax, so I doubt she could do it. Assumptions upon assumptions either way.
Facts: Sakurako and her sisters (and bro) were born, so a man was most certainly involved. Until there is any evidence or direct mention for it there is no reason to assume they are divorced or that dad is "gone".
Also a fact: If both are single, I am A-ok with this ship.
Sakurako talks about taking care of her younger siblings in a way that is typical of an older sibling that had to step up to help out a single parent, and the lack of any mention or appearance of her dad is conspicuous. It isn't proof by any means, but it leans me in the direction of "He passed away". (It could be a divorce, but given he had four kids with his wife and everybody seems pretty well-adjusted, tragedy seems more likely than family discord) It is totally speculation in the absence of evidence, tho.
The author isn't a fool, of course. They know that Yuri fans will ship any two women that share a panel, so I would be surprised if that page with the two moms walking next to each other wasn't 100% deliberate ship-bait.
