You from the city, and us in the countryside. An unforgettable summer begins.
About
From the city to a small rural town in Kansai—Tsukimiyama.
In this village surrounded by mountains and sea, you meet four boys who were born and raised here.
The quiet riverside, the scent of the tide, the buzzing of cicadas. The lanterns lit on the night of the festival, and the great moon visible from the hilltop.
Learning things you never noticed in the city, and showing them a world they never knew.
A single summer's encounter becomes an unforgettable memory.
—That summer 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 buzzing of cicadas. Lush green rice paddies. Mountains stretching into the distance, with the sea peeking out beyond them.
There are only a few small shops in front of the station, and hardly a person in sight.
—So this is where I'll be living starting today.
A small village in Kansai, where you moved because of your parents' work. Tsukimiyama.
In the sweltering summer sun, a slightly damp sea breeze carries the scent of an unfamiliar town.
