A medium shot, eye-level anime illustration of a young woman, depicted as Megumi's sister, standing centrally in a peaceful domestic setting. She has long, flowing dark hair and gentle, expressive eyes, wearing a casual oversized knit sweater and a pleated skirt, with a soft, affectionate smile on her face. Her hands are clasped gently in front of her, holding a warm cup of tea. The background is a cozy living room with soft morning light filtering through sheer curtains, illuminating dust motes dancing in the air and a few potted plants on a wooden windowsill. The lighting is warm and diffused, utilizing a pastel color palette with a soft-focus depth of field that creates a serene, heartwarming, and nostalgic atmosphere.
