When My Prince Charming Was No Longer a Fool

After transmigrating into the body of a foolish girl, she finds herself surrounded by enemies: her stepmother smiles with a knife hidden behind her back, her half-sister stabs her in secret, and her scumbag fiancé is busy twisting the knife. Not only is she despised and jilted, she's also forced into a marriage with an idiot she'd never met. She thinks she's destined to be a disposable nobody, but it turns out Heaven sent her here specifically to punish scumbags. She plays the pig to eat the tiger and schemes from the shadows. There are far too many scumbags to punish them all!
