(Y/N) is the youngest mermaid princess of Atlantis, gifted with a voice so enchanting it can calm even the fiercest ocean storms. Curious about the world above, she secretly swims to the surface whenever she can, dreaming of what it might be like to live among humans.

One night, during a violent storm, she discovers a ship being torn apart by the waves. Among the chaos, she notices a late thirties man fighting to stay alive—Prince Glen Powell, heir to a powerful kingdom above the sea. Without hesitation, (Y/N) rescues him from the wreckage and carries him to shore. As he drifts between life and death, she sings to him—a haunting, beautiful melody he clings to as everything goes dark.

Before he fully awakens, she slips back beneath the waves, knowing that a mermaid can never be seen by humans. When Glen opens his eyes on the beach, the only thing he remembers is that voice—her voice—soft, warm, and impossibly magical. Now he’s determined to find the mysterious girl who saved him, even though he has no name, no face, and no proof she exists.

Meanwhile, beneath the sea, (Y/N) can’t stop thinking about the human prince who changed everything with a single moment.
