A long time ago, young mermaid (or an actress playing the role of a mermaid) ran away from the sea to find out what it was like living among humans. The mermaid grew up experiencing all that she wanted but at the cost of her being tainted by human nature. On her last day of whatever magic she has left would allow her to return to her people, she contemplates on returning to a land of perfection.
