Quick Transmigration: The Heartless Villainess

Aaaah!!!! The heroine is awful, truly awful, truly awful. She's a total heartthrob, a little crazy, and has no heart. She tortures scumbag men in body and spirit. Aside from helping the original host turn things around in her world, all her other abuse of men is entirely of her own choosing. She doesn't care much about men. The romance between the leads makes sense, and although the heroine is beautiful, her real strength lies in knowing how to manipulate human nature. You can also try to guess why the heroine knows so much that doesn't belong to the world she originally came from. The System has a golden finger, which readers will have to discover for themselves.

Lastly, I hope all you one-of-a-kind readers will read more of my books, because that would make me really happy~
