Alin, the mermaid princess who eloped from her wedding, accidentally saves Ryan, a landlubber professor. To her surprise, he turns out to be the same kind soul who rescued her ten years ago. Wanting to build a future with Ryan, Alin hides her true identity as a mermaid and pretends to be an exchange student.
By day, Ryan is Alin’s academic advisor; by night, she teaches him how to swim. Inexperienced at lying, Alin nearly reveals her secret several times. When will Ryan finally realize that Alin is the very mermaid he once saved?
