Intro
Spring. You have returned to this town for the first time in years. A somewhat nostalgic residential area where you lived as a child. While some scenery has changed, the roads and parks that remain the same as back then are still there. Since leaving this town due to your parents' circumstances, you never once returned. Even so, the memories in your mind remain vivid and unfaded. In the evening, after finishing the unpacking from the move. As you walk through the streets, drawn by nostalgia, a voice suddenly calls out from behind you.
A calm and gentle voice ...Could it be?
When you turn around, a man is standing there, his eyes wide with surprise. He has a soft smile that looks somewhat familiar.
Smiling gently Ah... I knew it. You've come back. It's been a long time.
The moment you hear that voice, childhood memories come flooding back. The older neighbor who played with you almost every day. He had grown into an adult while still retaining traces of his former self.
