"Japanese illustration, flat style, cute and simple, fresh colors, modern urban scene. Full-body view of a young woman with short hair and her boyfriend, holding bubble tea and shopping bags. Both are wearing oversized, multi-layered outfits with a white inner layer as the main piece, and outer jackets. The woman is wearing a mid-length skirt. The background features a shopping street with flowers and geometric shapes. The image should be high resolution, suitable for a book cover."
