Badass FLs get revenge on a cheating bastard. I thought it was a very interesting story with good character development.

Leticiel in "Her Royal Highness Seems to be Angry"
I recommend the light novel not the manga!!!

Because the manga is quite different, more absurd twisted & inferior than the novel and it portrays her much clueless, weaker & sexualized.
In the novel she bows to one and her whole toxic family + ex-fiance prince + the king are powerless against her.
