When Mo Zai, a teenager from the God of Death, lured hacker Chen Chen into the Songhe Pavilion of the God of Death, he met Jin Jun, a special police officer. Seven years later, special police officer Jin Jun was predicted to be in catastrophe by the God of Death, and Mo happened to be sent to become the God of Death to guide his soul. Between the funny interactions between the two, a grim reaper who looks cold but is actually soft-hearted, and a special police officer who looks strong but is actually gentle, the two have a secret love. When the catastrophe came, the young boy impulsively intervened in Jin Jun's life and death. The relationship between the two people was exposed. If they want to be together, either Mo will reincarnate into the realm of life and death, or Jin Jun will join Songhe Pavilion. While the two were still struggling with how to make a choice, Mo's past life memories before he became the God of Death were unearthed. The appearance of Li Shijie, a former lover or former enemy, caused a rift between the two. But at this time, Li Shijie is not a human being, but a 300-year-old ghost. With the help of Gao Yue, the boss of Songhe Pavilion (it is said that his previous life experience was very similar to that of Mo), Mo finally knew the truth of the year, left the death organization and became a human with sexual desire.
