Lin Wei is a modern gold medal salesman who accidentally slipped into an ancient sadistic novel and became a miserable heroine who was tortured both mentally and physically by the male protagonist. The system requires her to go through all the sadistic episodes before she can go home. But when she looked at the tasks of "jumping off buildings for love" and "digging out hearts and transplanting kidneys", she felt an occupational disease - these KPIs (key performance indicators) were set unreasonably! So, she began to use modern management methods to fall in love: sending a homemade Excel spreadsheet to the male protagonist to analyze the "love investment-output ratio", developing the jealous male protagonist into an "intentional customer", and making a "competitive product analysis report" for the vicious female partner. Finally, the male protagonist knelt in front of her and begged her not to leave. She took out a notebook and said, "Want to renew the contract? Fill out the satisfaction survey form first."
