(Transformation, romance between women)
They say a lovesick yandere falling for an ordinary person is a horror story.
Then a yandere falling for another yandere must be a cozy fairy tale: a dark fairy tale, that is. #JustKidding
Jiang Mengnan transmigrates into a book as a yandere heiress. To change the heroine's future of chopping people up and ending up in prison, she stays home, does nothing, and refuses to follow the main plot.
To cut ties with the heroine, she saves the heroine's seriously ill older sister.
As they spend time together, Mengnan's yandere instincts kick in, and she threatens her:
"Luo Bingyu, you wouldn't want me to stop paying your sister's medical bills, would you?"
But she never expected the other woman to be a yandere too.
"Then Bingyu will sell herself to you~ You can have me tonight."
And in the end, she gets thoroughly devoured.
