The rules of the mermaid families were the same as humans, whereby the legitimate son had to inherit the throne. However, Lan Jingke's younger brother, Lan Yaoguang, was still a young kid. Therefore, the throne had to either be inherited by Lan Jingke or the uncle of the Lan family.
Of course, Lan Jingke did not want to let go of her family's throne, so she planned to inherit the throne first. However, there was a condition. She needed to find a very capable fiancé first before she was able to inherit the throne.
Although Lan Jingke was very pretty, she possessed the characteristics of a man. She was very forthright and robust. Though she had a lot of friends in the mermaid family, she could not find anyone that was capable enough of being her fiancé. However, it so happened that the severely injured Di Fuyi had suddenly appeared in front of her. What was more unexpected was the fact that Di Fuyi had lost his memories. He had even forgotten his own identity.
