Chen Xiaoshi, a partner of a listed company, was tricked by her friend and boss Teacher Liu into falling from the rooftop of the 16th floor during a company executive gathering. She accidentally traveled back in time from her thirties to the time when she was taking her junior high school entrance exam, only to find that a twin sister who looked exactly like her appeared out of thin air at home. Family, friends, and teachers were never surprised by this, as if they were twins. Chen Xiaoshi wanted to find out everything, and started a game in this world that may be misplaced.
Purpose: Re-evaluate my thirteenth years from the perspective of thirty years old, and how old I am is the real me.
