Jiang Mingyue married into the Marquis of Jing'an's household as the daughter of a court physician. For three years, while her husband, Pei Xiuyuan, was away fighting at the frontier, she managed the household and cared for her mother-in-law, enduring every hardship in silence. When Pei Xiuyuan finally returned victorious, he brought along Song Wan'er, a woman who claimed to have saved his life, and insisted on taking her into the household as his equal wife. Framed by her mother-in-law and Song Wan'er working together, Jiang Mingyue was divorced and driven out. At last, during a flower-viewing banquet, she revealed her true identity: the Mingyue Princess, personally granted her title by the late emperor, and a surviving descendant of the imperial family. The villains were all punished, she divorced Pei Xiuyuan, and began a brand-new life.
