I’m looking for a female lead novel where the male lead wrongs the female lead, and has to spend a lot of time getting her back. Something like https://www.novelupdates.com/series/the-world-of-the-pirate-consort/ where ML realizes his love for FL too late
The Dreamer in the Spring Boudoir is kind of like that, I think. The ML doesn't try to redeem himself yet as he isn't in love yet but I think it's leading to that.. https://www.novelupdates.com/series/the-dreamer-in-the-spring-boudoir/
I want to say that Shiro Buta has an initial plot similar to your request. the male lead is a competent young lad who was turned off by the MC (female lead) who is fat and treats everyone horribly. MC discovers her previous memory and works hard to become a better person and loses weight... the series gets more complicated from there. https://www.novelupdates.com/series/tensei-saki-ga-shoujo-manga-no-shiro-buta-reijou-datta/ As a fat individual I kind of don't like the fat shaming, but at the same time, I understand the pain...
Phoenix Overlooking the World – Who Dares to Touch My Abandoned Empress Worst novel with your typical slag asshole ml who killed mc and her child. He is worst than ex husband that mc take revenge on your typical revenge or second chance novel. Mc forgive him despite being killing and destroy her kindom, her child and her. The Two-Faced Venerate Emperor- male lead betray mc and kill her child. MC become weak. She was cure or save by second male lead. Male lead trying to geting back with her.
