Reincarnation/ isekai I’ve READ

It’s been a while but I believe she reincarnates and tries to have a better relationship with her step family than that from before her death

Mc transported to the after story of a novel she read after her two siblings died. She was promised to see them again. She takes the place of the shotgun wedding wife of the ML. The children of his first love are actually the reincarnation of her siblings
5/10 translation a bit weird. And genetics too lol

MC has been reincarnated multiple times. The first time was as a villainess who only has bad endings. Since she was reborn at a young age she tried to change her fate - only to “die” in a carriage accident. After another life & death she’s reincarnated once again into the same chara- but post accident and with the villainess reputation of the OG
