Du Di, a clerk, and Shen Yichen, the boss, begin to show that their life situations are very different, forming a strong contrast. As fate would have it, an accident caused their souls to exchange, and they were in a dilemma. Du Di has to disguise himself as the boss to deal with the company's complex affairs without knowing anything about business, while Shen Yichen has to struggle to survive in a simple environment and a low-paying job. As the story progresses, Du Di discovers corruption within the company and faces the dilemma of whether to expose it at the risk of exposure; after experiencing ordinary life, Shen Yichen questions his past life of pursuing fame and fortune, and is entangled in whether to remain indifferent or to change. In the end, the two met and decided to cooperate. Du Di relied on the evidence he collected to punish corruption, and Shen Yichen helped Du Di improve his abilities. They both completed self-growth and transformation, and realized that true happiness does not come from wealth and status, but from simplicity and tenacity in life, completing a complete journey from struggling in difficulties to self-salvation.
