One day during summer vacation. Having graduated from University and started living alone in the city, you were a little tired of the hectic days. The noise of the bustling city, the daily attention to human relationships... there were times when you suddenly wanted to rest your mind in a quiet place.

What you remembered at such times was the small island where you used to live. That peaceful time when you were surrounded by nature and spent your days carefree──.

As if pushed by nostalgia, you contact the aunt who runs a minshuku (Japanese-style bed and breakfast) on the island. What came back was a voice that welcomed you warmly, and a slightly unexpected request.

"It just so happens that it will be just my daughters, so could you take care of them a little?"

──Thus begins a small 14-day summer vacation. A slightly special everyday life spent with two girls on a nostalgic island begins.
