Professor, I'm Your Swimming Instructor

After fleeing an arranged royal marriage, mermaid princess Alin rescues Ryan, a professor who once showed her kindness long ago. Hoping to stay close to him, she conceals her ocean origins and enrolls as a visiting student. Ryan guides her through campus life, while Alin becomes his secret swimming coach after class. But with every close call, her hidden tail—and the truth of their past—comes closer to the surface.
