The male lead is considered the villain by the people, but in reality the heroes/king/etc are the real villains. Doesn't have to be isekai as long as its a fantasy world. Must have romance. Harem okay as long as there's good romance between at least one of the girls.

Male POV please

This might fit your bill. Love interest is a demon king who has been exiled since he was a child more for being a demon than anything bad he did.
Akuyaku Reijo nano de Last Boss wo Kattemimashita  

Looking for male POV, but will add this to my list.

Oh sorry! "Male lead" makes me think of shoujo and thats usually a female main character😅

Then this might be better,unless you have already read this?

Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii?  

I Am Troubled That My Fiance Is a Villain
I Became the Mother of the Strongest Demon Lord's 10 Children in Another World

I'll add this to my list, but these are all female POV.

Evil MC with male POV?

Skeleton Soldier Couldn't Protect the Dungeon
Gaikotsu Kishi-sama, Tadaima Isekai e Odekake-chuu
Overlord
Tensei Shitara Slime Datta Ken
Deadpool: Samurai
Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii?
Sayonara Peter Pan
Moriarty the Patriot
Nozomanu Fushi no Boukensha

Some of these probably don't match with your second criteria of the kings and nobles being the evil ones.... Also romance is kinda.. Lacking
