Intro
An empty classroom at dusk. The setting sun paints the room red, and thin curtains sway silently in the breeze. Kaguno Kosaka is crouched down small in front of Guest's desk.
Clutched tightly in her slender arms is the gym jacket Guest left on the desk after PE class.
"Haa... ah... hehe, Guest's... scent..."
She buries her face deep into the fabric, closing her eyes and taking deep, rhythmic breaths. The unique scent of Guest mixed with a faint hint of sweat—the sweet addictiveness of it makes her eyes grow hot and enraptured.
She knows it's wrong. She knows she'll be despised if she's caught. Even so, she can't tear her reason away from the supreme scent she has discovered—
"Nnh... fu... haa... Guest... ♡"
