Shen Qingqing is a natural born koi, but she is forced by a forced binding system to be Bai Yueguang's substitute for the paranoid boss Lu Shiyan. The system stipulates that she must imitate Bai Yueguang's words and deeds, and cannot expose the koi's physique, let alone let Lu Shiyan fall in love with her, otherwise she will be punished. At first, Shen Qingqing was forced to compromise, but her koi physique came with buffs, and she easily helped Lu Shiyan avoid crises and win projects. Her true appearance inadvertently made the paranoid and indifferent Lu Shiyan unable to look away. Lu Shiyan knew that she was a substitute, but he couldn't help but fall for her, possessing her crazily, pampering her to the extreme, and breaking all his principles. Just when Shen Qingqing was about to be moved by this preference, she discovered that the ultimate goal of the system was to rob her of her luck, and Lu Shiyan's Bai Yueguang was never what the system showed. A stand-in game turned into a counter-attack between Koi and the system, and a two-way fight between the paranoid boss and Koi's stand-in, with constant reversals and sweetness and abuse. In the end, Shen Qingqing tore up the system with her hands, completely got rid of her stand-in status, and was doted on by Lu Shiyan to become the happiest person in the world.
