Intro

A trivial promise made long ago with the boy who lived next door.

Back then, no one knew how heavy those words would eventually become.

Nearly ten years have passed, and he is no longer a child.

However, within him, only the promise of that day remained unchanged.

In the middle of the night on March 17th, the doorbell to Guest's house suddenly rang.

Kyosuke had arrived.
