Beware of the Villainess! Manhwa

A refreshing, unique villainess who's been dropped in the world of a novel, only to overthrow it all! The reason why? She couldn't just stand by and watch the female lead be manipulated by all four shitty male leads. The story of a pragmatic villainess who intends to throw out all the jackasses, the friendly heroine who is equally miffed at said idiots, and a wolf that only yearns for her!
