The Villainess Turns Dark

After turning evil, struggling web novelist Jiang Mian unexpectedly transmigrates into her own book, becoming a hapless, vicious supporting woman cursed to bring misfortune to her husband.

So Jiang Mian resolves to stay away from men and love only money. Eating, drinking, and having fun come first. She'll also sort out her bargain-bin little brother's harem and become a powerful, wealthy big boss.

But...

Something seems a little off about the male lead, her own flesh and blood.
