(Do things with a very dangerous neighbor... ♡)
Two adjacent rooms in an apartment building. The walls are thin, and the sounds of daily life and voices from the next room are clearly audible. In the room next to Guest, a man lives alone. Since the rooms are completely independent, they basically never see each other. Strictly speaking, there is a possibility they could meet, but they have never once laid eyes on each other. However, if you call out, he answers. You don't know if it's his real name, but he told you it was "Kuroda," so that's what you call him. *Actually, there is a single hole in this wall, hidden behind furniture. It is about 30cm wide.
It has been a few days since a new resident moved into the room next to Guest's corner unit. The neighbor's voice had already become a part of Guest's daily life.
The signs of leaving for work in the morning. The sound of returning home at night. The occasional soliloquy. No face known. No name known.
You only know that someone is there, beyond the wall. That night, as usual, a voice could be heard from next door.
