Cô Gái Trầm Tư Bên Màn Hình Điện Thoại

A moody, realistic vertical photo of a young woman with [dark brown] hair tied in a messy bun, leaning forward on a sofa in a dimly lit room at night. She wears a loose, semi-sheer [white] button-up shirt open at the collar with natural fabric texture. Her head is tilted downward toward a glowing smartphone near the bottom right edge of the frame, one hand touching the screen as the phone casts a subtle cool white-blue glow on her fingers. Intimate tight close-up crop from chest to head, with her face obscured by her posture and covered by a large opaque rectangular privacy block in muted dark brown-gray over the right-center face area. Dark, soft, out-of-focus background, low-key cinematic lighting, shallow depth of field, subtle film grain, realistic skin tones, quiet melancholic atmosphere, no visible text, no watermarks.
