"Generate a realistic photo featuring a teenage Japanese girl sitting on a chair in a living room. She should be holding a smartphone and looking out the window with a slightly surprised expression on her face. The living room should be well-lit and bright, indicating it is daytime. The atmosphere should be warm and inviting. Ensure the details of the room, such as furniture and decor, are visible but not overpowering. The girl should have distinctive Japanese facial features and appropriate attire for a casual indoor setting."
