Shanghai from 1916 to 1949, a deep love burning in the torrent of the times.
Tong Yueming, a fallen princess, and Shen Feng, the son of a shipping king, are the most special childhood sweethearts in Shanghai. He laughed and cursed, but protected her; she was cold and tough, and was his only "nemesis". From the frolics in the alley to the ups and downs of the business world, from forced separation to reunion at the end of the war, they spent half their lives explaining that the most affectionate protection is to become each other's comrades and armor. When the flames of war spread across the country, he sneaked into the underground economic front and dealt with the storm; she used her industry as a cover to build a secret passage. When the family and country are broken, the boys and girls of the past stand side by side in the smoke of gunfire - this is not only love in troubled times, but also a dual rush of faith and life. From childhood sweethearts to lovers of war. See how they wrote their personal joys and sorrows in the ups and downs of Shanghai into the spring and autumn of their family and country. `
