Shen Zhaozhao, a kindergarten teacher, dies and transmigrates into a novel, becoming the vicious female supporting character who is married to the villain Pei Jin. The original Shen Zhaozhao and Pei Jin have an agreement—Shen Zhaozhao is acting as the replacement for Pei Jin's white moonlight Wen Lu. To avoid the original Shen Zhaozhao's fate of being locked up in Pei Jin's basement, the former kindergarten teacher uses her child-rearing skills to "tame" Pei Jin, ultimately helping him escape from his fate as the villain.
