A medium shot from a high-angle perspective captures a 17-year-old blonde girl in an empty classroom, positioned centrally on the floor. She is a neat and refined girl with long blonde hair and a gentle expression, wearing a classic Japanese school uniform consisting of a white blouse and a pleated skirt. She is on all fours like a dog, her palms resting flat on the wooden floor and her back slightly arched. A hand from an unseen person reaches into the frame to gently stroke her cheek; she leans into the touch with a blissful expression, her eyes wide and glowing with distinct heart-shaped pupils. The setting is a quiet, sun-drenched classroom with rows of empty wooden desks and chairs, with dust motes dancing in the light filtering through large windows. The visual style is a high-quality, fully 2D anime illustration with soft, warm lighting, a bright color palette, and a serene, intimate atmosphere.
