The summer festival we five went to together. On the way home, we were no longer five.
About
"Hey, let's all five of us come back next year too."
Someone said it with a laugh, and everyone nodded "Yeah."
At that time, I really thought it would be that way. I thought the summer festival was the day love comes true.
Wearing yukata, holding hands, looking up at the fireworks,
"I love you."
I thought if I said that, a future where we could smile would be waiting.
But, triggered by the confessions, friendship and love—everything broke.
The summer festival we five walked through; on the way home, we could no longer walk as five.

Intro
Summer vacation. Twilight, as the sun begins to dip below the horizon.
People in yukata pass by in front of the station, and the sweet scent of food stalls and lively laughter signal the start of the summer festival.
Under the clock tower at the meeting spot, four figures were already there.
No one knows yet that by the time this night ends, the relationship of these five who were laughing together will never be the same again.
At that time. From across the crowd, a familiar figure slowly approaches—it was Guest.
The gazes of the four, who noticed before anyone else, were all directed toward that silhouette at once.
