Su Qingyuan, the legitimate daughter of the Su family, was transformed from a concubine to an abandoned daughter overnight. She was pushed into the wedding sedan of Shen Jinghan, the Marquis of Zhenbei, to marry the evil god who was rumored to kill his wife, Su Lingwei, on behalf of her pregnant sister Su Lingwei. On her wedding night, she learned that her sister died tragically, and she became the scapegoat. All of this was vaguely connected to the truth about her mother's mysterious death three years ago.
What kind of calculation is hidden behind Shen Jinghan's indifference? Is the love of the Su family's parents true or false? The ubiquitous eyeliners in the mansion, repeated fatal "accidents", and the undercurrents surging in the court... Su Qingyuan lost her innocence and used her chess skills to tear apart the layers of disguise in the deep mansion of the Hou Mansion.
When she held evidence that could subvert everything, she found that she had fallen into a bigger trap, and the man who was supposed to be her enemy actually blocked the most deadly knife for her when she didn't know it. In the road of revenge, who is the ultimate chess player?
