Lin Che, a provincial top student, and Jiang Chen, a rich second-generation playboy, were forced to exchange their souls by the "Reincarnation Tree" on a thunderstorm night that only happens once in a century. Lin Che entered Jiang Chen's body and was forced to face the internal conspiracy of the wealthy family, the indifferent family affection piled up with money, and the misplaced love that began with lies between her business marriage partner Su Wanqing; Jiang Chen fell into Lin Che's low-income life, bearing heavy academic pressure and the simple and burning expectations of his mother.
In the process of adapting to each other's identities, Lin Che used her wisdom to secretly investigate Jiang Chen's uncle Jiang Hantao's conspiracy to seize power, and grew from a "problem solver" who only knew how to study to a decision-maker who knew how to protect others; Jiang Chen was touched by Lin's mother's unconditional love, relied on his gifted social skills to solve school bullying for "himself", and found the value of being needed in taking responsibility.
However, Jiang Hantao noticed something unusual and hired a magician to try to imprison the two souls permanently. A decisive battle involving life, death and soul ownership began. In the final trial, Lin Che must learn to "live for yourself" and make major seemingly selfish choices; Jiang Chen must complete a pure sacrifice of "responsible for others".
When the souls finally returned to their original places, everything seemed to be back to where it started, but the two of them had completely changed. Lin Che put aside her fruitless love and started a new life of her own; Jiang Chen took the initiative to join the grassroots and turned that unforgettable experience into responsibility. They stole each other's lives, but in the trial of fate, they accidentally redeemed their true selves. Under the gaze of Samsara Wood, a new trialist has emerged.
