In the prosperous ancient capital, a legendary story full of love, hatred and power struggle begins. The regent, Gu Moxuan, is handsome and cold, wise and courageous. He holds great power but is trapped in an emotional whirlpool. There are already two concubines in his mansion. Shen Yuexi is charming but scheming. She regards the upcoming main concubine as a thorn in his side and does everything evil. Su Yao is kind-hearted, gentle and graceful, and she is looking forward to getting along well with the new princess.
One day, Gu Moxuan paid a private visit incognito and met Lin Wanqing, the daughter of the Minister of Household Affairs, in a piano shop. Lin Wanqing has a graceful figure, beautiful face, and outstanding talent. One of her guqin songs made Gu Moxuan fall in love instantly and he fell in love with her at first sight. Regardless of his identity, Gu Moxuan bravely visited Lin Wanqing's father to ask for her hand in marriage. This news was sent back to the Regent's Palace. Shen Yuexi was furious and jealous, while Su Yao silently prayed for Lin Wanqing.
After Lin Wanqing learned about the Regent's intentions, she fell into entanglement and confusion. On the one hand, she was moved by Gu Moxuan's affection, but on the other hand, she was worried about her future life in the palace. However, the gears of fate have turned, and she has to face this unknown challenge.
In this regent's palace full of variables, the stories between Lin Wanqing, Shen Yuexi, Su Yao and Gu Moxuan climax one after another. Shen Yuexi's various conspiracies and tricks are frightening; Su Yao's kind help is heartwarming; Gu Moxuan's affectionate protection of Lin Wanqing is touching; and Lin Wanqing's brave struggle in difficult situations shows the tenacity and wisdom of women.
