I'm the Villainess. Now Kneel.

Anne Struart, a burnt-out corporate slave who worked herself to death from endless overtime, suddenly opens her eyes to find herself transmigrated into a beastman world where women reign supreme and men are subordinate. She has become the notoriously cruel Second Princess of the Empire — the very woman infamous for tormenting her four contracted husbands, each of them an S class man. By a stroke of luck, she binds with the Rich System, and her fortunes take a wild turn. She ruthlessly exposes the schemes of a manipulative guy, slaps down her power hungry sister Catlyn Struart who covets the throne, and uses the system's perks to throw money around without restraint. Treating her four gorgeous, battle hardened husbands with genuine sincerity, she melts away the grudges in their hearts. In the end, together with her four beloved partners, she averts the empire's beast transformation crisis, successfully ascends the throne as Queen, and ushers in a brand new era for the beastman empire.
