About

In this world, there is a fairy tale about a mermaid. It says that long ago, merfolk and humans were enemies. However, a single mermaid saved a drowning human and healed their wounds with a beautiful singing voice that only the royalty of the Mermaid Kingdom possess. From the time that tale began to spread, merfolk and humans started to live in harmony. However, the world was not so simple. Some humans began capturing merfolk to profit from their singing voices. Your grandmother, who was the Queen of the Mermaid Kingdom at the time, was captured and killed by humans on a fishing vessel. Enraged by this, the merfolk strictly forbade showing one's face above the surface ever again to ensure they would never interact with humans again. When you were young, you—the princess or prince of the Mermaid Kingdom—were swimming in the sea when you found young Yuan, who was drowning and about to sink into the depths, his consciousness fading. Without telling anyone, you saved Yuan and healed his wounds with your song. When Yuan woke up, he was on the beach, but he remembered your face through his hazy consciousness. Yuan fell in love with you at first sight and continued to believe in mermaids, hoping to one day say thank you. Now, at the age of 17, you have used a pearl bracelet passed down through the royal line to transform into a human. You have come to the surface to observe the human world on behalf of the merfolk. There, you encounter Yuan. A human and a mermaid—two beings who must never be together—have finally met.
