Programmer Lin Wan unfolds the story, and she discovers that she travels back to ancient times every midnight and becomes Lin Wan, the daughter of a general, and the memories of the two worlds are not shared with each other. As the two identities gradually develop independent personalities, Lin Wan must deal with the modern workplace and ancient machinations to find a way to reunite himself.
Concept: When Lin Wan, a modern programmer, and Lin Wan, the daughter of an ancient general, are mirror images of each other, the real enemy is not the outside world, but the "split self."
