Directed by Jin Hyuk and written by Park Ji-eun, the series aired on SBS from November 16, 2016, to January 25, 2017, consisting of 20 episodes. The show stars Jun Ji-hyun as Shim Cheong, a mermaid from the Joseon era, and Lee Min-ho as Heo Joon-jae, a modern-day con artist.
The narrative begins in the late 16th century with a historical tale about a mermaid who is captured by fishermen. The story follows Kim Dam-ryeong (played by Lee Min-ho), a county magistrate who shows compassion for the mermaid and releases her back into the ocean.

Joon-jae is initially intrigued by Shim Cheong due to her priceless jade bracelet but soon becomes captivated by her innocence and charm. As their relationship evolves, they face various challenges, including Joon-jae's greedy stepmother and a rival for his affections, Cha Shi-ah (Shin Hye-sun), a researcher dealing with ancient artifacts. The series artfully blends humor with drama as Shim Cheong navigates the complexities of human life while helping Joon-jae evade danger.
