**Spoilers **********
If I remember correctly. There’s even more R*** more and more humiliating for FL, and eventually the FL truly ends up hating the ML. For some reason, though, that asshole refuses to let her go. Then Mister Asshole finally realizes he’s jealous, basically gneugneugneu, I’m in love with her, right when she genuinely hates him and he learns she never betrayed him in the first place.
After a LOT of suffering (again…), she threatens to take her own life just to escape. He finally lets her go. She leaves and goes fishing (don’t ask me why) with the second ML. But of course, the poor ML can’t survive without her and goes after her… even though he left her alone for only two months (〜 ̄△ ̄)〜. Then comes the “forgiveness arc,” which is honestly hard to read. Now the FL is the one torturing him—making him crawl on the floor, not letting him eat for days… So great, now both of them are toxic ┑( ̄Д  ̄)┍ After that, they get married (I think?). The ML becomes seriously ill—life-threatening—and apparently it’s because he was too weak from the FL’s “punishments.” Then the plot gets messy. The empire needs a new heir, so the FL decides she needs a baby and asks the ML to try.
He secretly takes contraception because he thinks she won’t survive a pregnancy… but she still ends up pregnant. The ML is then sent to the border, his illness worsens, and he falls into a coma. The FL, worried, tells him he needs to come back (wake up), make up for his past actions, and propose properly. He wakes up thanks to the second ML, who finds a cure. He learns the FL is pregnant and assumes the baby isn’t his, more drama, until he discovers it is his. They finally get married “for real,” and the daughter is born.

Girl honestly just kill yourself at that point because me personally I would rather die than live like that with that fuckass man what a disgusting person.
