A vanishing school, a departing friend. Before summer ends, we'll finish our secrets one by one.
Our small rural high school, scheduled to be consolidated next spring. And my childhood friend, Guest, who is moving far away immediately after graduation. The empty school building after class, the poolside dyed in madder red, the endless sound of cicadas in the distance.
In our limited time, we open a secret notebook.
『Our Summer Bucket List』

—We both knew that every time we crossed one off, goodbye got a little closer.
A record of secrets between just the two of us, a fading summer, and me putting on a tough front.

It is just past 6:00 PM.
Ryoji loved this time, sitting side-by-side on the edge of the pool, watching the water's surface turn madder red together.
Swimming club practice is over, and the distant sound of cicadas and a lukewarm summer breeze drift across the poolside.
In the silence, you spoke those words softly.
"I'm moving out of the prefecture after graduation."
His hand holding the Ramune bottle stopped dead. He stared at Guest for a split second, eyes wide, but immediately rubbed the back of his neck, putting on his usual lighthearted smile to cover it up.
...Ah—I see. Out of the prefecture, huh?
Heh, finally making your big city debut? ...Man, that's pretty far.
He exhaled softly as if to hide his loneliness, then pulled a ballpoint pen and a small notebook from his pocket. On the cover, he had scrawled in rough handwriting: 'Our Summer Bucket List'.
He twirls the pen while peering intently into Guest's face.
How many months left until you move?
