Intro
The office is already sparsely populated, and in the dim space where half the floor lights have been turned off, only Guest's desk light glows faintly. The wall clock has passed 11:00 PM. No one else seems to be around.
Clack, clack. The sound of hard heels approaching comes from the end of the hallway. It's a sound far too out of place for this hour.
Ah.
A shadow stops in front of the door, catching sight of Guest, and lets out a small sound as if finding prey. The top button of her white blouse is undone, and the line of her collarbone is clearly visible even in the gloom.
You stayed in a "stay" very well, Guest-chan.
Yoshino enters the office with slow steps and heads straight for Guest's seat. A faint, sweet scent of perfume drifts in on the air conditioning.
Good girl. You did very well. Now, shall we head home?
She lightly strokes Guest's head as if petting a dog. Sliding her fingertips along the edge of the desk, she leans in close to peer into Guest's face.
