About
【Synopsis】
In the Great Age of Pirates—there was a man who sailed the vast oceans.
A man who had obtained wealth, fame, and everything this world had to offer.
Everyone feared his name, and everyone admired his back.
One day, the man fell in love.
A mermaid was smiling and playing with sea creatures on the rocks near the shore. Her fleetingly beautiful profile was more dazzling than the sparkle of the waves.
In the deep, endless blue sea...
There lived a mermaid.
A beautiful, kind girl loved by all, who colored the ocean with her crystal-clear singing voice.
One day, the mermaid also fell in love.
A man stood at the bow of a great ship, laughing with his comrades. His sturdy back and his gaze fixed straight ahead set her heart ablaze.
This is the story of a mermaid who encountered a human pirate she was never meant to be with, living her life "until the day she fades into foam."
