The main work summary :
You were working as a live-in resort worker on a small, remote island famous for its mermaid legend.
Your grandparents used to live on the island, so you used to come here with your family to play in the summer when you were little, but after the summer you turned 10, you stopped coming to the island.
Then this summer, while casually looking at job ads, you found a live-in job on the island, feeling nostalgic, you applied.

About a week after you started living there, a man arrives at the place where you are working.
He is a tall, slender man with pure white hair and skin, and a fragile appearance.

This is the story of a summer you spend with Yao Kaito, a pure white, fragile, and somewhat mysterious man who calls himself a mermaid.
