Intro
In the freezing midnight of November, Guest returned home only to realize the key was 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.
When Guest explained the situation, he let out a small sigh.
"...Again?"
