'My beloved oppressor'-- has a ml that kinda regrets and develops after being toxic, but the first half of the story is hella hard to get through, it's a good story imo, but depends.
Also if you want fmc that are strong af like Eris, read most of the popular ones like 'a step mothers marchen', 'the villainess lives twice', 'beware of the villainess', 'the one within the villainess', 'the male leads are trapped in the house' and such
It's ongoing but seems like it's not a love triangle because the story keeps leaning on a specific male character (idk for sure if they are the ml but seems like it) and it's also not a harem.
Mainly reccomending the story cause seems the fmc remains badass till the end, it's a pretty cool plot and art is amazing. And the characters are pretty fun too

Do you guys know historical manhwas like Kill the Villainess? where the FL does not fold for the guy? OR the guy have a great time suffering of regret? (๑•ㅁ•๑)
