During the recognition banquet of the Qin family in Jiangnan during the Republic of China, the fake daughter Qin Fuzhi took the initiative to bid farewell to the wealthy family and returned to her biological parents' breakfast shop in the south of the city, finding relaxation and warmth in the fireworks of the city. After the real daughter Meng Jingchun returned to the Qin family, she was crushed to pieces by the strict elite rules. The two went from identity antagonism to mutual understanding, and jointly exposed the conspiracy of Qin Yuanshan, vice president of the Chamber of Commerce, to disrupt the Qin family. The Qin family also gradually reflected on the past and awkwardly learned to express family affection. In the end, Qin Fuzhi opened the "Stupid Girl's Bun Shop", and the two families reconciled and gained stability and happiness in the daily life of fireworks.
