I just read I'm a villanous daughter, so I'm going to keep the last boss and I was wondering if yall know a manga where the male mc hates the story's villainess but gradually falls for her?

Any recommendations is ok just no ecchi/hentai ones thanksss 🙂

This one should be somewhat what you’re looking for: I swear I won’t Bother You Again

Though he’s only one of the male mcs

Would it be fine if he didn't know the she is the villainess?

in need of romance?
uncommon, sad, sweet

Doctor Elise
Endo and Kobayashi's Live Commentary on the Villainess
What It Takes to be a Villainess

The spinoff of the popular Destruction Flag Otome, I Reincarnated into an Otome Game as a Villainess With Only Destruction Flags... In a Dire Situation!? Verge of Destruction Arc, will probably head down this route.

There's even more if you take out the bit about the male character hating the female character before falling in love. For instance, Accomplishments of the Duke's Daughter, Lady Rose Wants to Be a Commoner, For Certain Reasons, the Villainess Noble Lady Will Live Her Post-Engagement Annulment Life Freely, and The Banished Villainess! all have villainesses who get their "just desserts", and then it turns out that they've had other male characters interested in them all along. Oh, and Of Course, I'll Claim Palimony!

And, she's not exactly a villainess, but the protagonist of The Abandoned Empress is hated by the main male lead before her reincarnation (to the point that she's unjustly murdered by him).
