In the summer of 20 16, Lin Jingyun, a Chinese-American who grew up in France, a food critic and a senior editor of Gourmet magazine, came to Shanghai to visit food and start a journey of seeking roots. At this time, the Lins' old house has been transformed into a restaurant, which is full of precious old Shanghai newspapers and old things, recording the stories of that year. Lin Jingyun stumbled upon a diary and opened it. It tells the story of a girl named Tianying's ups and downs of love legend. In Shanghai in the late 1920s, Hong's gang, Lin's chaebol and Xu's police station stood on the beach, calm and undercurrent. In the theater, Tian Ying pretended to be a male makeup artist, 9-year-old Hong, and took to the stage to save the scene. But she doesn't want to be an instant hit and become a famous figure. Mr. Luo of the Red Gang and Xu Xingcheng, the son of the Xu family, fell in love at first sight, showing their strengths. The Eagle Seed of Love thought that the gentle and elegant Xu Xingcheng would be a sweet first love, but it was a scam. It happened that Luo, who had always been domineering, met unexpectedly and got entangled. Unconsciously, Tianying's inner emotional balance is also quietly changing. At the same time, Duan Tianci regarded Tianying as his fiancee and imprisoned her in the name of protection, but she broke through the kind kidnapping and drew a clear line with her. Hong's daughter secretly loves Luo and makes things difficult for her everywhere, but she is moved by her true temperament and her rival in love becomes her best friend.
