Architect Gu Shen and painter Lin Xuxu are about to get married. Deeply in love with each other, both of them hide their own timidity and unease. Haunted by the shadows of her original family, Lin Xuxu fears the uncertainties of marriage and time, and suspects that Gu Shen's proposal is just going through the motions. Meanwhile, Gu Shen, who appears calm and restrained, has carried the trauma of his father's departure since childhood. Terrified that he will repeat the same mistakes and hurt the woman he loves, he can only bury all his love and panic deep down, never opening up his true feelings.
On the eve of their wedding, a candid confrontation finally lets the two catch a glimpse of each other's true feelings hidden beneath restraint, clears the rift in their hearts, and solidifies their resolve to stay together. But a sudden lightning strike on a rainy night unexpectedly swaps their souls, leaving them trapped in each other's bodies.
Since then, the aloof architect has dwelt in the body of the gentle painter, while the sensitive painter resides in the frame of the composed architect. In this misaligned life, they heal each other, adapt to one another, untangle the obsessions rooted in their original families, and shed the restrained timidity they once masked themselves with. The fears they once dared not voice, the true hearts they dared not lay bare, and the future they dared not hope for—all gradually find release in the intimacy of their intertwined souls.
