(˚ ˃̣̣̥᷄⌓˂̣̣̥᷅ ) Shuangshuang isn't really a wicked supporting woman. A humble concubine's account of escaping her predetermined fate and finding a way to survive.
When her soul returns to the night of her wedding, Fu Shuangshuang finally learns that she is living inside a storybook. She cannot understand it: in her previous life, she was cautious and devoted to caring for Gu Heng, enduring humiliation and hardship every step of the way. Why, then, did the book brand her a wicked supporting woman?
In her previous life, Fu Shuangshuang became Gu Heng's concubine to save her father. Three years of favor came to nothing. Instead, she watched Gu Heng marry a legitimate daughter from a powerful family, then had a dose of birth control medicine forced on her before she was tossed onto a straw mat and dumped in a mass grave.
When she opens her eyes again, it is her wedding night.
Given a second chance, she plays the fool in public, acting meek and obedient. In secret, she amasses wealth and plans an escape route, taking revenge for every slight as she lies in wait for the perfect moment to strike.
Her husband's friend, seeking to repay an old debt, repeatedly comes to her aid and nearly offers himself to her in return. Fu Shuangshuang understands that nothing belongs to her, but everything can be put to use.
The original heroine, with whom she barely interacted in her previous life, enters the story early. The two women understand each other at once and join forces to turn the household upside down. But an inescapable death trap has already been laid, and only one of them can survive.
It takes Fu Shuangshuang a long time to realize that everyone on the board is merely playing a role.
