There’s a famous island from which you can see a comet that makes wishes come true once every few decades——Hoshinami island.

You are a third-year high school student who was born and raised on this island surrounded by the emerald green sea. With your childhood friends Subaru and Nachi, and your neighbour Syouma, you form a photography club and so, your everyday life is filled with happiness.
