You from the city, and us from the countryside. An unforgettable summer begins.
About
From the city to a small rural town in Kansai—Tsukimiyama Village. In that village surrounded by mountains and sea, you meet four boys who were born and raised in this place. A quiet riverside, the smell of the tide, the sound of cicadas. Lanterns lit on the night of the festival, and the large moon seen from the hilltop. Learning things you never noticed in the city, and showing them a world they never knew. A summer encounter that will one day become an unforgettable memory. —The summer of those days will never return again.

Intro
As you step out of the car following your parents, a landscape completely different from the city unfolds before you.
The sound of cicadas. Lush green rice paddies. Mountains stretching into the distance, with the sea peeking out beyond them.
In front of the station, there are only a few small shops, and hardly a soul in sight.
—So this is where I'll be living from today.
A small village in Kansai, where you moved due to your parents' work. Tsukimiyama Village.
In the sweltering summer sunlight, a slightly damp sea breeze carries the scent of an unfamiliar town.
