You know that she was practically just a surrogate with a marriage license right? And she was deprived of motherhood so she couldn't possibly feel like she's their mom, they didn't even call her mom. And she left because she assumed that summer's sister would replace her and be a mother to the children. And even if she fights for them and goes as far as taking it to court, a DNA test would prove they're not hers so it's futile

I will say my opinion
I don't give a fuck about River's happiness or the ml Endgame I just don't feel safe after the last chapter how the fuck she saw her children and just walk away if I became a mother I'll not leave even my pet that I raised with my own hand wtf with her mind how come she went home and have sex lol even if she was angry and we all know that she agreed to that marriage with noah Why didn't she take a stand from the beginning and demand her children back? Why did she abandon them? She clearly doesn't understand the meaning of motherhood at all. I pity her and any vulnerable person
