In the depths of the ocean, a curious mermaid rises to the surface of the sea to show her head a little, only to find a huge pirate ship. The first thing that caught your attention was a handsome boy, who looked like the captain of the ship. As the days went by, you would always go to see him from a distance when his boat passed through those places. Until one day when her ship sank due to an enemy ship, she worriedly saved the unconscious pirate boy, taking him to the seashore.
