The Villain Demands I Love Him
That sure was interesting. I was already hooked when I heard it's the ML that gets reincarnated but that's only the beginning. The good stuff is how he decides to deal with it. Villainesses always plan things out carefully and every move is calculated, but that's not the case with this guy! The moment he wakes up he grabs a horse and runs straight to her. Still in his PJ's, he cries, drops to his knees, and begs for her hand in marriage. Better yet, he asks her which limb he should cut off to prove he's sincere, tells her she can beat him, and offers to literally give her everything he has and more. If that doesn't sound like a top tier manhwa to you then I don't know of anything that would. EDIT: Gets sorta mediocre after the bit I just described.
The Evil Lady's Hero
I dropped this aaagggeesss ago because I thought it would become smut, turns out it's not. There's just 2 chapters when it randomly becomes ecchi and afterwards it's back to normal. Ishid is occasionally slightly iffy but normally he's an absolute cutie and I love him. It's nice MC is a reasonable person, she's not emotionally constipated or has a victim complex.
I Adopted A Villainous Dad
If I'm not misremembering this was good. MC is actively doing stuff to help her situation and wants to stay with daddy. Dad's cute too.
