Shen Zhixia, the daughter of a guilty minister, became a palace maid after her family was wronged. She just wanted to live a stable life, but she accidentally bumped into the prince Xiao Jue in the Qionghua Gallery, and the cinnabar ink on the dragon robe was splashed, which became the beginning of the bond between the two.
Xiao Jue, the crown prince of Dayin, whose mother and concubine died young, grew up in a tolerant family amidst the jealousy of his father and the strife of courtiers. He hides his loneliness under his cold and stern appearance. Seeing that Shen Zhixia was gentle on the outside and strong on the inside, knew medicine, was good at restoring ancient books, and showed extraordinary wisdom in several crises, he transferred her to the East Palace, and from "attention" to "temptation", he silently blocked her from the palace's secret arrows.
The palace is like a chess game. The three princes' covetousness, Concubine Liu's frame-up, and the prime minister's lust for power have drawn the two into a whirlpool of disputes over the throne and family injustices. Shen Zhixia is no longer a palace maid who only seeks to protect herself. She relies on her medical skills to save the Queen Mother and solve the epidemic, and uses her wisdom to investigate unjust cases and help Xiao Jue. Xiao Jue is also willing to break the shackles of class for her, defend her shortcomings in public, and sacrifice her life to protect each other. From the "Prince" to the "Emperor", he always regards her as his only weakness and armor.
From the first meeting in the Qionghua Gallery to the companionship of the East Palace, from the palace maid to the crown prince, and then to the emperor and empress who share the power of the country, they crossed the identity gap, experienced the test of life and death, and finally wrote a legendary story under the willow wall of the palace, "holding the son's hand and growing old together with him".
