I'm basically looking for a manga/manhua/manhwa where the Male villian falls in love with female lead, it can be shoujo/jousei/romance and even with smut. Of course no Yaoi/Yuri please.
By Male villian, I mean that the male villian must have done something horrible like being ruthless/killing people etc. If possible, the manga should focus more on romance.
So far this is what I read which fits the type of manga I'm looking for.

1. Can't Lose You
2. Hadashi de Bara wo Fume
3. Basara
4. Haou Airen
5. Gu Fang bu zi Shang (It's a manhua that's good and fits the theme)

I'm just trying to find more of this kind of manga/manhua I hope you have some to suggest.

Masca
Shinigamihime no Saikon
Oboreru Knife, kinda
Kuroorihime to Kawaki no Ou

DONDAKEE!!
