Gu Wanzhi, the daughter of the Gu family, was betrayed by her fianc é Fu Yizhen on the eve of her wedding. Feeling heartbroken, Gu Wanzhi met the true ruler of the Fu family, Fu Sichen, by chance. Fu Sichen regarded Gu Wanzhi as his double for the white moonlight and wanted to marry her, but he never expected that he had already fallen in love with Gu Wanzhi. However, Fu Yizhen maliciously instigated their relationship and let Gu Wanzhi know the truth. Gu Wanzhi and Fu Sichen broke up, and Fu Sichen regretted it and began to make up for Gu Wanzhi. He also had to be wary of Shi Yi, who also liked Gu Wanzhi. In the end, the two of them resolved their misunderstanding and reconciled, and Shi Yi completed their love. Fu Sichen also discovered that his white moonlight at the time was also Gu Wanzhi.
