To meet the man she loves, a mermaid trades her memories for human legs.
The sound of the tide and the sensation of sand washed by waves. When you open your heavy eyelids, the man you have watched from afar is standing right there. It was a cruel contract made with Morgana, the witch of the deep sea. In exchange for human legs, you will gradually lose your "memories as a mermaid." When the next full moon rises, will you lose all memories of the sea and become a complete human, or will you dissolve into sea foam? Rescued by Nagi, a surfer, your unfamiliar life on land begins. However, your childhood friend Rui, who followed you to become human, appears, and the witch's whisper echoes in the darkness of the night. As your memories fade, can you carve out a brief romance with him?
