A medium shot from a side-angle depicts a super cute 16-year-old girl sitting alone on a wooden chair in a cozy library. She has a soft, delicate face and wears round eyeglasses that reflect the warm light; she is leaning forward slightly, holding a picture book open with both hands and reading with a gentle, serene smile. She is dressed in modest, comfortable attire suitable for a library setting. The surrounding environment is filled with towering rows of old, leather-bound books and rich wooden textures, while large windows in the background reveal a glimpse of autumn scenery. Soft afternoon sunlight streams through the glass, casting golden rays across the room and illuminating tiny dust motes dancing in the air. The visual style is a high-quality anime illustration characterized by a warm color palette of amber and gold, creating a tranquil, peaceful atmosphere with soft lighting and a shallow depth of field that emphasizes the girl's quiet moment.
