Anyone who knows something like "You got into the wrong House, Villain" "Villainess Reverses The Hourglass" Something light but substantial... satisfying. ??? Anyways, something like that. Thanks
Level 99 Villainous Daughter - This one is kind of a slice of life from an OP Villian I Am Troubled That My Fiance Is a Villain - Romance, where the fiance is SERIOUSLY a villain, but tones it back for the main character. BUT it still leaks out here and there. Villain Heal: The Villainess’s Plan to Heal a Broken Heart - Really good romance, that just kinda has villain in the title. Should really be Yandere instead of Villain. (Completed) Akuyaku Reijou wa Danna-sama wo Yasesasetai - Truly an appropriately wronged Villainess. This story is SUPER cute, and has a great amount of character growth and plot development. Lost sleep powering through this one. (Completed) This is my best of list, hope this gets you started down the path of villiany!
The Lazy King - Some guys sleeps his way into being the ultimate villain Boss. Whoops? It's actually really good despite how BAD the description sounds.
