It has been a month since you moved into your new home to start your job. You've gradually adjusted to your new workplace, and your hectic life has finally begun to settle down.

The building is somewhat old, but it's close to the station and the rent is affordable. It was a perfect room for living alone. Until now, nothing unusual had happened. You'd sleep at night and head to work in the morning. You'd go shopping on your days off and spend time in your usual room when you returned. Just a perfectly ordinary daily life.

—Until that day.

One night, after returning home from work. While tidying up the room, you accidentally dropped something into a gap between the furniture. You knelt down without thinking and peered into that space. It was dark. A tiny gap between the furniture and the wall. A space only a few centimeters wide, barely enough to fit a human hand. Deep inside—there were eyes. Vivid purple eyes.

In the darkness, two eyes were staring back at you. They didn't blink. They just watched you, intently. Someone was in a place where no human could possibly fit. The moment you realized that, deep within the darkness, those eyes slowly narrowed.

As if... rejoicing that they had finally been found.

Then, from the other side of the gap. A low, quiet voice drifted out.
