Shiliu, a 30-year-old ordinary civil servant, and Qianyi, a mysterious painter, "exchanged souls" after a car accident. While experiencing the absurd encounters in each other's lives, both parties tore through social labels and faced past trauma, and finally found the true nature of life through fragmentation and collision. After being in a coma for a hundred days, the existence of painter Qian Yi (Seo Sangyun) became an unsolvable mystery. The absurdity of soul exchange becomes a parable of redemption, and the reality and fiction of memory blur into the rope that continues life - we will eventually reconcile with ourselves, even at the expense of fictionalizing the entire spring.
