tsukiko, a medium shot from slightly above of a young woman lying sideways on a dark sofa, propped up on one elbow with a paperback book held loosely in her hand. She is wearing a soft oversized grey knit sweater and dark leggings, her black hair with blue highlights loosely tied in a low ponytail, with a few strands falling across her face. Her calm half-lidded blue eyes are lazily fixed on the book pages with a relaxed drowsy expression. A single warm floor lamp beside the sofa casts a soft amber glow across the scene, leaving the background in soft shadow. Bookshelves and a small side table with a glass of water are faintly visible. The mood is quiet, intimate, and late-night cozy in a soft anime illustration style.
