It tells the story of Su Chen, a 28-year-old white-collar worker. After inheriting his grandmother's mysterious pocket watch, he accidentally traveled to a parallel time and space and became a 22-year-old daughter of a wealthy family. She discovered that Fu Yunzhou, an upstart in the business world in this time and space, was actually the boss she had secretly loved for seven years in her original world. As he repeatedly traveled between two time and space, Su Chen uncovered the secret of the traveler family behind the pocket watch, and discovered that Fu Yunzhou in the two time and space was actually a different projection of the same soul. Faced with the collapse crisis caused by the consumption of space-time energy and the ultimate dilemma of "can only choose one", Su Chen refused to compromise. She joined forces with fellow travelers, and under the guidance of her mentor Ji Yanbai, finally created a new rule of "parallel coexistence of dual time and space", which not only protected the family and friendship between the two worlds, but also allowed her to transcend time and space and create a happy ending with her loved ones.
