Shen Jiming, the director of the technical department, and Jiang Wan, the marketing manager, are well-known "workplace enemies" in the company. They are at odds with each other every day over the core project "Star Track". A strange thunderstorm caused the rivals to unexpectedly switch bodies.
In order to keep their jobs, the two were forced to sign a "cohabitation agreement" and clumsily impersonate each other. In Shen Jiming's body, Jiang Wan discovered that this cold-faced director would tenderly comfort her cancer-stricken mother late at night; Shen Jiming, with Jiang Wan's identity, understood that under her strong appearance, she hid the forbearance of being sucked by her original family.
From the daily routine of acting like a chicken and a dog, to working together to find out the insider of the project, they got a glimpse of each other's tenderness in each other's lives that had never been shown to others. When the thunderstorm comes again and the body returns to its original position on the celebration night, the drunken two break through the defense line and kiss.
This fantastic exchange allows them, who are incompatible with each other, to understand each other's hardness and tenderness. From tit-for-tat to soul-to-soul interdependence, it turns out that the best love is to see through the appearance and see the real each other - just like the "star paths" will eventually intersect, and they also find each other's light in their misplaced lives.
