I just want to point out that
In essence, A-Chan is agreeing to an arranged marriage with Koharu's father for the sake of Koharu and their unborn children, at the request of her future lover. Remember, this is a culture where arranged marriages are still a thing, they are just usually arranged by the parents, not your childhood friend whom you are going to move in with once your husband dies in an accident.
Just because it's common practice, it doesn't make bad thing any less bad. I'd even say it being arranged by your childhood friend and future lover makes it worse in fact
Just gonna say Rin does realize A-Chan loves the guy and her daughters. They chose a route where they can all be happy in the end, it’s not really an arranged marriage.
what you said makes no sense whatsoever, it was an arranged marriage and I find it really weird how A-chan loves the man and Rin chan too! because she also has all the memories every time the time-line resets!
like, no matter if she loves the poor sod that is only used for this D to get thous 2 children because aperently that D and babys are the saviour of thous two lesbian couples!!! yap!…………the more I think about it the more shity this story becames ugh really the worst way to end in an happy gay couple story >.>
