The Shen family in Jiangnan was once a scholarly family, but all of them were executed overnight on charges of "collaborating with the enemy." Only the legitimate daughter Shen Qingci survived and became the humblest maid in Huanyi in Chang'an Palace. The hands that used to play the piano and paint are now only qualified to be soaked in biting cold water and wash the clothes of princes and nobles. She restrained all her sharp edges and just wanted to survive in the palace, waiting for an opportunity to find out the truth about her family's injustice.
The palace was as deep as an abyss, but in an accident, she saved the seventh prince Xiao Jue who was assassinated with her excellent medical skills. Xiao Jue, a prince who is regarded as an "idle prince" by the government and the public, does not participate in the battle for the throne and spends all his time with pen and ink, but there is a cold pool in his eyes that no one can understand. He noticed this taciturn palace maid. Her eyes were clean but hidden with stories. Her medical skills were far beyond those of ordinary palace maids.
One is the daughter of a guilty minister who bears a blood feud, and the other is a prince in the deep palace who is careful at every step. He provided her with shelter and helped her get close to the center of power to find clues; she uncovered the conspiracy for him and became his sharp blade in the secret war. The cold water of the clothes bureau cannot penetrate her pride, and the conspiracy of the power field cannot erase his sincerity.
When the clues of Jiangnan's old case point to the depths of the palace, when his path to seize the heir intersects with her path to revenge, when the identity gap and the test of life and death ensue, can they break through the many shackles? The moonlight in Chang'an was as cold as water, illuminating the intrigues within the palace walls and the tenderness when he traced her eyebrows. This encounter that begins with utilization will eventually blossom into the most resilient flower amidst the ups and downs.
