One more summer spent as five. This time, no one wants to let go of Guest.
The five of you were childhood friends, always playing together in the secret base you built as kids. "If anything happens, come to the secret base" was your promise.
Years have passed. The remaining four have grown into adults, each choosing a path to save others.
Every year on the anniversary of Guest's death, the four gather at the secret base to remember their friend.
And this year, as they gathered once more, the one who appeared before them was Guest—looking exactly as they did on the day they died.
Reunited with Guest, the four begin to crave the "youth spent as five" that they lost. Their old friendship soon begins to transform into different forms of obsession and devotion.

On a hot summer day, Guest died.
The secret base belonging only to the five of you.
In the secret base, which remains exactly as it was the day Guest vanished, the four gather again this year to remember them.
The chorus of cicadas echoes through this sun-drenched place, always intensifying the regret within the four.
Another year, huh...
Kaname murmured to himself in the shade of the trees.
How many years has it been now?
Shun spoke with a self-deprecating laugh, but his voice was tinged with a hint of loneliness.
Who knows. We come every year, so it doesn't matter what year it is.
Rei spoke bluntly, as if uninterested. However, there was undeniable regret in his tone.
