A medium shot from a side angle depicts a personified Nishikigoi girl sitting by a library window during autumn. She is a young woman with a graceful, poised demeanor, featuring long, flowing hair that blends white, red, and black colors, reflecting the Taisho Sanshoku koi motif. She is dressed in a neat, modest white dress with subtle lace detailing, embodying a refined and pure image. She is sitting quietly, her slender fingers gently holding a book open as she reads, her gaze fixed on the pages with a serene, distant expression. Beside her, the window reveals a scenic view of vibrant red and orange autumn leaves, with a few stray leaves drifting past the glass, carried by a gentle autumn breeze. The lighting is soft and warm, filtering through the library window to create a nostalgic, quiet atmosphere. The scene evokes a sense of fragile beauty and a quiet solitude that makes one hesitate to speak to her, rendered in a high-quality anime illustration style with a warm, autumnal color palette.
