When Su Qingran woke up, she entered a wealthy family's abuse novel and became a cannon fodder stand-in for the paranoid villain Gu Yanchen who could not survive more than three chapters. The original owner was kept and tortured by Bai Yueguang because he looked like Gu Yanchen, and eventually died miserably. Fortunately, she was bound to the "plot correction system" and could see the death prompt in advance. In order to survive, Su Qingran worked step by step, deliberately avoiding all death plots, and worked hard to get rid of the label of stand-in. However, her sobriety, independence and unusualness attracted Gu Yanchen's attention. The initial curiosity gradually turned into unstoppable sincerity. Just when the relationship between the two was heating up, the heroine Lin Weiwei in the original book was unexpectedly reborn and returned with the memories of her past life, vowing to take back everything that belongs to her, including Gu Yanchen. A battle surrounding love and conspiracy, sincerity and use begins. Su Qingran not only needs to protect her own life, but also needs to keep this hard-won sincerity.
