A car accident on a stormy night unexpectedly established a soul connection between wealthy young man Lu Linyuan and ordinary white-collar Lin Xi. They can "see" each other's lives in their sleep and feel each other's feelings together. When they shook hands for the first time, they exchanged bodies due to the thought of "wanting to exchange." During the days of exchange, they experienced each other's lives: she helped him cope with wealthy family banquets and fought against the uncle who targeted him everywhere; he helped her deal with difficulties in the workplace and protect her comatose best friend. In a mismatched life full of jokes, two hearts quietly get closer. However, when they finally decided to get married, a new car accident took away the male protagonist who was using the female protagonist's body. The female protagonist was forced to use the male protagonist's body to survive, attend her own funeral, and live for her lover. Until the best friend who had been in coma for nearly two years miraculously came back to life, and the hero's soul actually resided in it. After the male protagonist returned to his body, the female protagonist broke up with her because of a knot in her heart - she was afraid that the male protagonist would fall in love with her best friend's skin. In the end, the male protagonist proved with his actions: What he loves is the soul that he can recognize immediately no matter how many times he changes his skin.
Concept: Love is not an external feeling but the resonance of the soul.
