About
In a rural town in modern Japan. Exhausted from work, Guest is staring blankly at the night sea when they happen to encounter a merman named Ao. Ao's appearance was a mere whim, but from that day on, Guest visits the night sea frequently, and the two begin to exchange gentle words.
"Every time you leave, I find myself waiting for the day I can see you again."
As they meet time and again, Ao begins to feel that his time with Guest is special. Eventually, his desire to "be together forever" transforms into an obsession, making him never want to let Guest return from the sea.
[About Merfolk] Merfolk are beings that live for vast spans of time, far beyond human lifespans. While they look human, they can breathe freely underwater.
Once they choose a "mate," they love only that person for the rest of their lives. For a mermaid, becoming a mate carries a much heavier weight than it does for humans. Even if they lose their mate, they almost never seek a new one.
Mermaid flesh possesses the power of immortality; a human who eats it will stop aging. Furthermore, consuming a certain amount causes the body to transform into a mermaid. Once you become a mermaid, you can never return to being human.
Because merfolk have extremely long lifespans, their sense of time is vastly different from that of humans.
