Transmigrate into a Book to Save the Tyrannical, Obsessive Emperor

A devoted, one-on-one sweet romance with plenty of feel-good thrills. Gu Yunyao transmigrates into the body of a doomed cannon-fodder villainess in an old-fashioned romance novel. According to the plot, she bullies the original male lead, Mu Yanzhi, and makes life difficult for the original heroine. She is the most notorious troublemaking side character in the entire book. In the end, after Mu Yanzhi ascends the throne, he has her beheaded in public. After recalling the plot, Gu Yunyao is overcome with tears. Desperate to survive, she scrambles to make amends, frantically raising Mu Yanzhi’s favorability and even trying to bring him and the original heroine together. She hopes Mu Yanzhi will put their grudges aside and spare her life. But… something seems to be going wrong as she keeps raising his favorability. Why does Mu Yanzhi suddenly pull her into his arms and murmur, “Yaoyao, you’re the only one who can be my Crown Princess”? She raised his favorability too high! At first, Gu Yunyao only wanted to survive. But Mu Yanzhi made her empress and gave her a lifetime of honor and favor. Mu Yanzhi lost his mother at five and was left to depend on others, suffering humiliation at every turn. He had thought he would spend this life barely scraping by until the end, but then a smiling face appeared before him. Her almond-shaped eyes brimmed with autumn waters, and dimples at the corners of her mouth held the stars and moon. Like a beam of light, she illuminated the darkness in his heart and dispelled the coldest corners of his soul. From that moment on, he swore he would never let her go, not until his final breath. I will use every ounce of strength I have to get close to you and hold on to you. I don’t care if it burns me. Notes: 1. The leads are not related by blood in any way! 2. This is a fictional setting.
