The chairman of the Chu Group traveled through time and space through a pocket watch and came to the place three years ago where he had a conflict with Yin Yiyi, missed the opportunity to see his mother for the last time, and accidentally lost the pocket watch. Yin Yiyi picked up the pocket watch and wanted to return it, but accidentally changed time and space to send Chu Xiaoting back to the present. Chu Xiaoting, who was looking for the pocket watch, bought a luxury store to help Yin Yiyi out, but the two did not recognize each other. At the same time, Chu Xiaoting asked Yin Yiyi to help him find the strange girl as a creditor. After some misunderstandings, the two recognized each other, but the pocket watch was gone. Chu Xiaoting stayed at Yin Yiyi's house, and in the process he and Yin Yiyi gradually felt the love from each other. When the pocket watch finally returned to Chu Xiaoting's hands after going through hardships, he learned that re-activating the pocket watch might lose the opportunity to be with Yin Yiyi forever. In order to fulfill Chu Xiaoting, Yin Yiyi gave up her love and triggered the pocket watch mechanism to make Chu Xiaoting travel back to three years ago. In the new time and space, Chu Xiaoting and Yin Yiyi finally reunited.
