Yang Yunzhi transmigrates into a book, ending up in a tragic novel she'd read as the heroine's doomed younger sister, a cannon-fodder character who dies right at the beginning.
The System tells her that she can return to the real world only if she changes the heroine's original ending.
So Yang Yunzhi has no choice but to change the plot like crazy.
Her stepmother wants to set the heroine up with a womanizer?
Take the heroine to a brothel. Check.
Her stepmother wants to punish the heroine using her scumbag father?
Act weak to win Grandma's sympathy. Check.
Her stepmother turns her attention to Yang Yunzhi instead?
Outsmart her stepmother. Check.
Later, even the Empress targets her.
After overcoming one obstacle after another, the heroine survives to the end of the novel.
Just as Yang Yunzhi excitedly prepares to return to her own world, the book's great villain blocks her way.
His eyes redden at the corners, tears glimmering in them. “Could you stay?”
Yang Yunzhi: ...Then I'll stay?
