The young girl Wei Mian accidentally traveled to modern times and possessed the body of a girl who committed suicide after being ignored. Being penniless, she could only start by setting up a stall to survive. She is thoughtful and perceptive, and can always see through disguises at the clues. She gradually makes a name for herself in Qingping City, exposing the fiancée of a wealthy businessman's plot to seize his family property, saving an international student who was abused by domestic violence, seeing through the scam of making money in the name of a master, and helping the victim recognize the true face of the person who cheated marriage and money, so that the grievances can be vindicated. On the surface, she is a freshman in the History Department of Qingping University, but privately she wanders between urban wealthy families, the business world and campus, insisting on doing good deeds and never changing her original intention.
