Realistic Japanese Classroom Selfie

Ultra-realistic candid smartphone selfie of a {argument name="subject" default="beautiful young East Asian woman"} sitting at a wooden desk in a {argument name="setting" default="bright Japanese classroom"}. She has shoulder-length straight dark brown hair with soft wispy bangs framing her face, natural makeup, clear fair skin, subtle pink lips, and a calm slightly dreamy expression. She rests her cheek gently against the back of her right hand, with her elbow placed on the desk, looking directly into the camera.
She is wearing a {argument name="clothing" default="loose white and navy blue Japanese-style school track jacket"} with dark navy panels, white piping details, ribbed cuffs, and a black collar. Her pose is relaxed and natural, as if casually taking a selfie during class.
On the wooden desk in front of her are an open textbook and a colorful Japanese-language manga/textbook with illustrated characters. In the background, there is a large green chalkboard with handwritten Japanese equations and notes, a wall-mounted air conditioner, large classroom windows with white curtains, and bright daylight streaming through the windows. A dark patterned school bag or jacket is visible on the right side.
