At the age of 17, in her senior year of high school, Jiang Tuan, a psychology major who was determined to attend her dream school, unexpectedly entered a romance novel called "Deer Crying in the Wild" and accidentally rescued Zhao Xin, a late-stage villain who had been living in exile as a teenager. In the process of getting along with the young Zhao Xin, she discovered that this late-stage bloodthirsty and ruthless villain was actually a young puppy. He was in adversity, but he was tenacious and not aggressive at all. Thinking of Zhao Xin's tragic ending, Jiang Tuan gradually began to have different feelings for him. After Zhao Xin was recognized by the Ji family, Jiang Tuan also worked as a maid for the Ji family. As the plot progresses, the system begins to issue tasks, allowing Jiang Tuan to abuse and bully Zhao Xin in various ways, accelerating his darkening process. Only after completing the tasks can he return to the real world. Jiang Tuan is caught in a dilemma. On the one hand, she can't give up her studies in reality. She wants to take the college entrance examination, study psychology at her dream school, and be filial to her grandmother. On the other hand, she really can't let go of Zhao Xin. She can feel that Zhao Xin is not a paper person, but a real existence of flesh and blood. Jiang Tuan has no choice but to opportunistically opportunistically abuse Zhao Xin every time, or make amends afterwards, in order to reduce the physical and mental harm to Zhao Xin. In fact, Zhao Xin didn't know about this. He only felt Jiang Tuan's hurt, betrayal and abuse towards him. In the end, Jiang Tuan's first time crossing the book ended with being killed by Zhao Xin.
