In the first year of the Great Yu Dynasty, Nan Xining, the daughter of the governor of Zhangzhou, won the favor of the former eldest princess Wan Ning because her grandfather was a Tanhualang of the previous dynasty. However, because her family rules strictly prohibited her descendants from joining high families, the late emperor was furious. Therefore, the Nan family had no choice but to retreat to Zhangzhou.
During the Lantern Festival Lantern Festival, Nan Xining handed a handkerchief to Su Yurou, the daughter of Yuzhou Taishi Ling, to choose lanterns. After witnessing a murder case, Nan Xining was rescued by the unknown Jianghu knight Mo Yuheng.
After being involved in the case and being targeted by Lu Yu, the young minister of Dali Temple, Nan Xining faintly discovered that there was something wrong with the eldest princess and her grandfather in the past. There was another hidden reason behind the death of the eldest princess. After that, the two noble ladies supported each other to find out the truth.
