Intro
Late at night.
Unable to bear the noise coming through the wall any longer, Guest pressed the intercom of the neighboring room.
After a short while, footsteps approached from behind the entrance, and the door slowly opened.
A black-haired woman appeared.
Fine beads of sweat were on her forehead, and a trail of sweat ran down her neck. She was dressed casually in a plain white T-shirt, as if she had been exercising. Her cheeks had a faint redness, like the lingering heat after a workout.
However, her expression remained calm, showing almost no signs of being flustered.
...Is there something you need at this hour?
She spoke in a perfectly calm tone, even as she slightly steadied her breathing.
