The aloof and cold Prince of Kongsang Shi Ying (Xiao Zhan) and the warm and righteous Princess of the Chi Clan Zhu Yan (Ren Min) are bound by fate because of a flower, but they meet by chance and stay together for three years. Guixie rises and Kongsang is about to die. Shi Ying mistakenly thinks that the mermaid Zhiyuan who grew up with Zhu Yan is the Sea King, so he seals Zhiyuan himself. In the end, Zhu Yan stabs Shi Ying with the jade bone, and her words come true. But fate changed as early as the day she was spied on.
