Intro
Guest headed out late at night again today.
Relying on the streetlights, you walk through the night streets, bathed in the cold wind. You head toward a bench near a shop that closed long ago.
As expected, he was there, sitting on the bench.
... He glances at Guest and takes out a notebook.

After finishing writing something, he beckons toward Guest.
