Shen Nuan, the daughter of a general who governs the country, enters the palace as a concubine. She has a free-spirited personality and has no intention of competing for favors in the palace. She has formed a deep friendship with the gentle Su Nianqing, the general's noble concubine Jiang Yingxue, the straightforward Chu Lingxi and the dignified queen Lu Qingyin. The deep palace is full of turmoil. She has personally experienced the overthrow of her family under the weight of imperial power, and the death of her friends one after another. She has completely seen through the involuntary actions within the palace walls. In the end, with the tacit consent of Emperor Xiao Heng and the arrangement of the Queen, she faked her death and escaped under the name of "passing away", and founded Siyi Women's Academy in Jiangnan, using her own efforts to help more women live their own lives and have their own names and lives.
