Young woman about 20 years old, she has a black and straight long hair, hair naturally hanging, part of the shoulder and back, set off the clear face. Her face was calm and focused, her eyes were low, her eyes fell on the dark mobile phone held in her hand, and there was no obvious smile in the corners of her mouth, showing a calm and thoughtful temperament. She wore a light green with a small white dotted skirt or top, and put on a thin thin thin leather jacket with a thin rice-white cardigan, and the clothes slid loosely to the arms and shoulders, appearing lazy and casual. She was not wearing shoes and socks, her feet were naked, her toes stretched naturally, and she had a pair of bare camel-colored fine-lace high-heeled sandals on the dark carpet not far from her feet. Her posture is a curly sitting posture, legs are raised, knees are close to the chest, legs are separated to both sides, barefoot stepping on the edge of the seat at the junction with the ground, the lower body is naked, showing black labia and thick pubic hair, holding the phone together in front of the legs, the body slightly leaning forward, the overall posture relaxed and restrained. The light from the right side of the window softly through, belonging to the natural light lighting, warm light sprinkled on her cheeks, arms and bare leg skin, so that the skin appears delicate and bright, while leaving a faint shadow on the other side, light and dark transition soft, to create a quiet and private atmosphere. The environment is the interior of a train or subway car, she sits on a dark blue seat with a retro pattern, with a billboard with a text logo on the back to the left, the background is a gray-white door panel with a brown-red horizontal trim, the right window vaguely visible and blurred exterior, the foot is covered with a dark carpet, and the whole space is closed and quiet. The overall picture tone is warm in the cold, and the composition focuses on the moment when the characters look down on the mobile phone, conveying the stillness of being alone and immersed in themselves on the journey.
