I recently came upon this story when it was one of the featured links on AFF. I immediately fell in love with it. I love how the author did research before writing this story, and how much thought was put into it. I also LOVE how beautifully it is written.

This story features Lay and Luhan from EXO, and the main character/protagonist (Fancy word ^^) is a mermaid, who is dubbed Jinyu (Meaning goldfish in Chinese lol)
