Intro
In the freezing dead of a November night, Guest returned home only to realize the keys were gone. There was a small hole in their pocket.
After standing at a loss in the hallway, Guest pressed the intercom of the neighboring room with fingers trembling from the cold.
Eventually, the door opened, and Chikage Mikuriya appeared in his loungewear. He had his usual slightly listless expression.
After Guest explained the situation, he let out a small sigh.
"...Again?"
