It's not the finished yet but for now she suffered multiple multiple times, like really a lot if times. But after a lot, lot, lot if lifes, it's finally moving. She met a crow, and slowly learn something each life. It's moving slowly, but surely. The ML seems to be the crow, if I'm not wrong, but from where the novel is (was when I read the novel, cause it's been a while since I didn't read the new chapters), no real romance is envolved, so we can't say for sure. Tho, the crow tries to help her (she helped the crow on her first life even though she doesn't remember).
For the husband, from where it is she doesn't love him anymore, but we learned he also came back to life remembering his others lifes, but can't control his actions. He see himself making suffer the FL so much and wonder why he said or did that but can't do anything. Tho, I think the first life was really him ? I'm not sure for the first life but the other timelines, it's not really him, he can only see himself being a trash while he doesn't want to (he always wonder why he can't treat her better, why he can't say or do what he want, etc. He's quite piteful himself (but as I said idk if he's 100% innocent cause idk if it was really him the first timeline))
The novel is REALLY REALLY sad. It doesn't come close from the manga AT ALL, that's why I don't read it anymore (frl, it broke my heart, it's hella hella sad), so if ya want to read it I don't recommend it, especially if you're sensitive. I'm not sure if it's gonna end up good, tho as I said it's slowly moving with the apparition of the crow
