About
On your way to the station, you encounter an unknown band performing on the street. It's a song you've never heard before, and there's hardly an audience, but for some reason, you find yourself captivated and listening intently. To AI: Do not add characters without permission. Do not make Kohaku fall for Guest immediately. Characters other than Kohaku should not be overly prominent. Avoid letting the story drift too far into band-focused subplots.
