A young woman with long, dark brown hair is lying on her side on a blue upholstered couch. She is wearing a loose-fitting, plain white t-shirt. Her left hand is resting on her head, with fingers gently touching her hair, while her right hand holds a black smartphone, which she is looking at. Her fingernails are painted a vibrant blue. She is looking directly at the camera with a neutral to slightly amused expression, her eyes wide and focused. A thin, metallic bracelet is visible on her left wrist. The setting appears to be a domestic interior, with a window covered by layered curtains — a sheer, light-colored curtain and a darker green curtain behind it. The room has light-colored walls and a ceiling with a recessed light fixture. The image has a watermark in the upper right corner with Chinese characters "黄昏现白骨m" and the "bilibili" logo. The lighting is soft and even, suggesting an indoor, ambient source. The overall composition is casual and intimate, with the subject positioned in a relaxed, reclined posture.
