The heroine was reborn ten years ago and discovered that she was not the real daughter of a wealthy family, but an adopted "fake sister". In her previous life, she was pushed into depression by the so-called "perfect brother" and was treated as an outcast from a business marriage by her family and died tragically. After her rebirth, she looked in the mirror at the face that looked exactly like Bai Yueguang, the former hegemon, and suddenly smiled. Since everyone likes substitute literature, this time, she chose to be her own "stand-in" - sneaking into a rival company, becoming an undercover "green tea", and starting a close "squid game" with her brother's business empire. She wanted to tear that perfect home into pieces with her own hands.
