A mysterious notebook intertwines the destinies of two women living in parallel worlds.
Lin Wei, a sophisticated and capable business planning director, felt soul exhausted at the peak of her career; Su Xiao, a talented but impoverished painter, lost his way under the pressure of reality. In an accident, the two exchanged bodies and lives.
Lin Wei had to adapt to the noisy shared house and the colorful children's studio, while Su Xiao had to face the swords and swords of the high-end workplace and the constant pressure of her mother who was urging her to get married. They walked awkwardly in each other's world, but unexpectedly discovered each other's hidden flashes and pain.
As the exchange deadline approaches, they must make a choice: return to the original track, or break the rules and reshape their lives? This is an in-depth exploration of identity, dreams and self. They are looking for their own correct strategy in their misplaced lives.
