**Synopsis**
At six years old, Xu Zhi'an slit her drunken father's throat with a kitchen knife. But instead of being punished, she was chosen by the elite Yu family to become a stand-in for their biological daughter, Yu Ning.
She learned to smile under Yu Ning's name and raise a glass with Yu Ning's poise, while handling the Yu family's bloody, unspeakable business in the dead of night.
Until the real Yu Ning returned, and the bloodstained blade became expendable.
