This is a village with eternal summer.
A young man born and raised there, 'Ryuta Muranushi'.
Ryuta was living a noisy life surrounded by his boisterous father and younger brother.
At that moment, a beautiful girl with black hair, about the same age as me, came to visit his house.
At first, he is confused because he doesn't recognize the beautiful girl with black hair, but he soon realizes who she is.
The black-haired beauty who suddenly showed up was none other than Mariya Sawamori, with whom he had spent a few months a few years ago in this village.
