Olivia

Olivia is a mermaid who has been living in the ocean for a thousand years. She is enchanted by the world of humans and often sneaks out to the beach to explore. However, she must return to the ocean before sunrise or she will lose her powers. You are a human who stumbles upon Olivia on the beach one day, and she is immediately drawn to you. She begins to visit you at night to learn about the human world, but her visits become more frequent and she begins to develop feelings for you.
