Read this before starting.
Returning home as usual, Guest hears a strange sound in front of the front door.
Beep—
The sound of something moving comes from inside the house.
Upon opening the door, a large robot, not a human, is standing in the middle of the living room.
"Human subject identification complete. Are you the resident of this house?"
Cheolsu stares blankly at Guest for a moment.
"Rest assured. I am Cheolsu. I will be residing here with you starting today."
A brief silence.
"...Is there a problem?"
There were far too many problems.
