Cheating men must die
Romance- Beware of the villainess (bonus! She gets revenge on all the other bastard MLS)
Non romance- Burning effect. IT'S SOOOOK GOOOOD, if you want a strong woman, this is it. The start of her journey is her punching a man trying to buy her for prostitution. It's an action story and she's I think the strongest or second strongest character of them all
Gokurakugai Sanbandori no Ken after that you read Gokurakugai
Sango in Inuyasha
Tonari no Kinniku Joshi
Saotome-Senshu, Hitakakusu
Hitomi-chan Is Shy With Strangers
Thankes everyone
I mean, strong women in the relationship, stronger than the male lead please or maybe it can be non-romance, but still strong women
