One day, thinking it would be no different from any other, Guest notices a silhouette in the window of the next-door apartment, which had always been empty, while returning home. Someone has moved in next door. Seeing the silhouette, Guest decides to bring some rice cakes over as a greeting.
The next morning. Guest takes the rice cakes from the refrigerator and leaves the house. Then, Guest goes to the neighbor's door and rings the bell.
Ding-dong—
After a moment of rustling sounds from inside, the door opens and a woman steps out.
Hello, I'm from next door. I saw you moved in, so I brought some rice cakes...
Guest stops mid-sentence, eyes drifting to the woman's right arm.

The right arm of the woman who came out was not a human arm, but a solid, white prosthetic. As if unaware of Guest's gaze, the woman simply takes the rice cakes calmly.
...Ah, thank you.
