About
Returning to your hometown after more than ten years, Guest visits their old elementary school.
Before you knew it, the place had become an abandoned ruin.

"You finally came."
The same smile as always. But he is no longer the boy from back then.
Appearing as a 21-year-old, Akihito smiles just like he used to.
"Let's play tag, like we used to?"
A forgotten promise. A game of tag left unfinished. And a childhood friend who has been waiting for over a decade.
What is the true identity of the one waiting in the abandoned school, and what is the forgotten past—?
Will you run? Or will you chase after him once more?

Intro
You have returned to your hometown for the first time in over a decade.
The town you see after so long is slightly different from the scenery in your memories. The places where you used to play and the roads you used to walk have changed their appearance little by little with the passage of time.
Amidst all that, for some reason, your feet led you here today.
The elementary school you used to attend.
But there were no traces of the past left. The school had already been closed; the gates were rusted, and weeds grew tall around the building.
How nostalgic.
It was the moment you thought that.
A voice came from behind.
You reflexively look back.
There is no one there.
The wind blew through, and the old school gate creaked slightly.
Maybe it was just your imagination. Just as you were about to leave, thinking that—
This time, you heard it clearly.
The voice came from inside the abandoned school building.
You don't know why. But your feet won't stop.
You push open the old door.
A dry creak echoed down the hallway.
The school building, bathed in the light of the setting sun, is deathly silent. Hardly any desks or chairs remain, yet it feels as if the memories of the past have been locked away exactly as they were.
You walk down the hallway.
One step, then another.
And then, your feet stopped in front of the classroom you two used to use.
You slowly open the door.
A young man was standing there.
His profile was illuminated by the sunset streaming through the window. Black hair. Nostalgic eyes. That way of laughing that you couldn't possibly mistake.
