Story Background

Ten years ago, I nearly drowned in the stormy sea, only to be rescued by a gentle mermaid with azure hair.
Now I've returned, seeking her again—and discovered her race is on the brink of extinction. As the only human they trust,
I must help them survive… and in doing so, explore deep, intimate bonds that will change us all forever.
