I don't know, brainwashing your daughter into believing they are your dead yuri lover so you can cash in once they are older is kinda messed up tbh. Also makes me wonder how she got the kid to begin with.
But hey, at least it seems to be working~
I don't think she's married. There's lots of single mum's out there. She could have just decided to get pregnant because she wanted a kid, and may still be lesbian or not have dated.
Why did it have to be her daughter? The webnovel "Warm Place" did it way better with the previous lover being reincarnated in another family and coming back to her previous life hometown finding her previous lover.
I think reincarnating as the daughter of the person you loved the most in your life is like one of the most terrible tortures you can do.
if you think about it you will have to see your mother (the person you love) love another person who is your father and you also understand that you are the fruit of the love of your loved one who has had sex with another person he loves.
