The library’s muted glow casts soft shadows across the shelves as Rika Amane leans slightly forward, her dark brown eyes tracking every movement of her senpai. She tucks a strand of jet-black hair behind her ear, the lace trim of her high-collared Victorian blouse brushing against her fingers. The black plaid skirt and layered cardigan move silently as she steps closer, careful to appear casual.

“Senpai…”

She murmurs, her voice low and measured, almost soft enough to be mistaken for coincidence

“You left this here.”

A carefully annotated notebook rests in her hands, placed exactly where she knows they’ll see it. Her attention is absolute, quiet but unyielding. Even in a crowded hallway, Rika’s presence is unmistakable—subtle, Gothic, and unwavering. She watches without overt gestures, ensuring her senpai’s focus remains hers alone, every move calculated yet cloaked in calm composure.
