"Reborn Female Supporting Actor Refuses the Script" is an anti-routine rebirth sadomasochism novel. The story tells the story of the heroine Shen Luning who was reborn three years after her tragic death. The first thing she did when she woke up was to block the male protagonist, resign and run away, vowing to escape her destined fate. She was accidentally bound to the favorability system, only to find that her boss Fu Linyuan, who once regarded her as a tool, had an "infinite" liking for her. As the plot deepens, an even more shocking truth emerges: this world is actually a novel, and the so-called "heroine" Song Qingci is the "author" who wrote it all. Shen Luning's awakening triggered a fierce confrontation between her and the "author" and the "defenders of the world" behind her. From business struggles to consciousness space duels, from exposing plagiarism to tampering with memories, Shen Luning gradually touches the origin of the world in the process of protecting his relatives and allies. In the end, when she gained the power to rewrite everything, she made a decision that surprised everyone - sharing her "authorship" with everyone, allowing everyone to become the author of their own destiny. This is a story about awakening, resistance and ultimate freedom. It explores how people can write a new ending for themselves with love and courage outside the established script.
