Holy Crap! The Fake Heiress Hooks Nothing but Cannon Fodder

[Transmigrate into a book, System, fake and real heiresses, younger man, one-on-one and mutually devoted, strong female lead, secret identities, imaginative, mostly comedy]

Unlucky Jiang Qing transmigrates into a book.

She becomes the fake heiress who's about to be thrown out in three months.

The original girl is also a hopeless romantic who has managed to offend her entire family for the male lead.

Jiang Qing says, “This is a hopeless start. No dog would take this deal!”

The transmigration System says, “Complete the original story in her place and you'll receive a reward of one hundred million.”

Jiang Qing says, “No dog would take it? Then I'll take it! I'll take it, take it, take it, take it!”

And so Jiang Qing goes all in on her path as a wicked fake heiress.

But can somebody explain something to her?

Why, while she's fawning over the male lead, are the villains fighting to become her mistresses?

Her eldest brother, a CEO on the verge of bankruptcy, starts doting on his little sister once the company's crisis is resolved!

Her second brother, who was supposedly on his deathbed, suddenly gets better. He can punch a pig into the air and becomes her personal chef!

Her third brother, a faded top-tier star who had vanished from public view, makes a comeback and turns into her shadow!

Her fourth brother, who nearly grew mold from spending so much time in the lab, succeeds in his research and becomes her underling!

Jiang Qing realizes something is off and prepares to run for it.

But when she turns around, she sees the five cannon fodder characters she's drawn in standing obediently in a row, gazing at her with pleading eyes.

Jiang Qing: What can she do? She'll just spoil them!

But the closer she gets to the end, the more something feels wrong.

Wasn't she supposed to be playing the part of the cannon-fodder fake heiress? How did it turn into a story about the real heiress being doted on by everyone?
