The heroine Shen Zhaoning is a arrogant and aloof female bailiff (both of her parents were sacrificed police officers, she was trained strictly since she was a child, and she is used to hiding her softness with a cold face). She was transferred to the serious crime team due to a series of murders on a rainy night, and was forced to partner with the coquettish and funny second-generation rich man Gu Yanchuan (he worked as a policeman to experience life after his family went bankrupt, and used humor to cover up his inferiority complex). There were constant conflicts between the two in the early days. Gu's amusement broke Shen's aloof persona several times, and Shen's rigor also made Gu gradually more reliable. The murderer of the serial case was Shen's old high school acquaintance Lin Shenzhi (a yandere who turned into a black man. Due to lack of love in childhood, he regarded Shen as his only light, and turned into a black man and committed crimes after being rejected). Shen gradually uncovered the truth through the "Bailiff Intuition System" (a professional system that can restore clues and scenes), and teamed up with Gu to capture him and slap him elegantly in the face. During the process, the relationship between the two sprouted, and the sweet pet interaction was interspersed with suspenseful plots, and finally they came together.
