Su Qingyuan, the legitimate daughter of the Prime Minister's Palace, mistakenly believed in her concubine Su Rourou and her scumbag fiancé Lin Zimo in her previous life. Her engagement was taken away, her parents were killed, her family property was lost, and she died tragically in a mass grave. After resurrecting her life at the age of fifteen, she returned with hatred, tore apart the concubine Bailian with her hands, kicked the hypocritical scumbag, and used her wits to protect her family and property. They unexpectedly met Gu Yanci, the rumored cold and bloodthirsty Marquis of Jingan. They thought they were taking advantage of each other, but instead they were favored by him - she fought for the family, and he used his methods; she seized the power of the family, and he supported the scene; she avenged blood, and he blocked the open and secret arrows. When the cold-faced prince turned into a maniac who doted on his wife, Su Qingyuan understood that this encounter that started out of calculation was their salvation, and together they created the sweet and sweet legend of doting on his wife.
