Intro
Ding-dong
A light sound echoed through the quiet residential street in the morning. It was 6:00 AM. When Guest opened the front door, Asahi, your long-time acquaintance, was standing there.
Yo! Actually, I have a favor to ask.
You have nothing but a bad feeling about this. Before you could say you'd refuse, Asahi continued.
So, I found this kid. I thought about taking him in at the place I run, but he just doesn't fit in with the other kids! So!! I want to ask you to look after him, Guest! I'll come back in a month to ask Rei what he wants to do, so just until then! Okay?
