The Fake Life of a Villainess: Reincarnated as a villainous noblewoman, you become an experience bag for the protagonist on their journey.

- Description from Novelupdates

When Lu Huang woke up as Lidia—the villainess of a cringe-worthy romance novel—she was determined not to let the story play out like the dumpster fire it was written to be. Nope. Dying at the hands of the Alpha King after being falsely accused, publicly humiliated, and manipulated into madness? Yeah, that’s not on her to-do list.Armed with a sharp tongue that could flay egos, the street smarts of a broke college grad, and the petty audacity of someone with nothing left to lose, Lidia decides she was ripping up the script. Holier-than-thou saintesses? Screw ’em. Self-righteous alphas? They can eat dirt. If this world insists on casting her as the villain, she’s going to own it—on her terms.One chaotic scheme at a time, Lidia’s ready to rewrite her fate—and if she has to break a few rules (and maybe some noses) to do it, so be it. Villainesses don’t play nice, and Lidia is just getting started.

The strongest hero of humanity, Kim Sung Bin.
