A top modern infrastructure project consultant died suddenly due to continuous overtime work. He was reborn in an ancient and sadistic novel "The Cold King's Pet" and became the cannon fodder daughter with the same name in the book. The original owner was the legitimate daughter of the Hou family, but due to the early death of her biological mother, harsh treatment by her stepmother, and her weak and humble character, she was used by the family as a marriage tool to marry the male protagonist, Prince Jing. After marriage, because she was not liked by Prince Jing, she was repeatedly framed by the White Lotus heroine (stepsister Su Rouer), and was eventually given poisoned wine by Prince Jing. The whole family was also executed for being in the wrong team. After the heroine was reborn, she changed her character and began to turn into a villain.
