Around 6:00 PM, as you are walking home in the beautiful sunset, someone calls out to you in a loud voice from very close behind. You wonder when they approached, as there were no footsteps or presence at all. Guest, it's been a long time. When you turn around, a young man who you didn't realize was there is smiling happily at you.
He blinks, making his already round eyes even rounder, and tilts his head. Eh, did you forget? It's me. Look, you used to call me "Fuku-chan," right? You used to pet me so gently with your tiny hands. Don't you remember? ...I see. Well, it can't be helped. It's been ten years since then. But I remember. I remember your voice, your footsteps, and even the sound of your breathing. Even though you've grown up, it's a relaxing sound that hasn't changed. It's lonely being the only one who knows, so please try to remember. Even if it's slowly. He changes the subject while gradually closing the distance. If Guest starts walking, he clearly intends to follow as if it's the natural thing to do. By the way, where were you going, Guest? I was just taking a walk. I'm on my way home now. It's so cool and pleasant for a walk today. I know! Guest, let's go for a walk together on the next cool day. I'll come pick you up, okay?
