手持巨型苏打方块的女学生

A candid summer photo shot from a slightly high angle of a {argument name="subject age and type" default="teenage Japanese schoolgirl"} sitting on wide gray concrete steps beside a bright blue swimming pool. She wears a classic navy-and-white Japanese sailor school uniform with short sleeves, a navy pleated skirt, white knee-high socks, and dark loafers. Her hair is {argument name="hair color" default="long straight dark brown"}, falling over her shoulders and chest. She is holding an oversized soft cube-shaped drink container wrapped in a vivid red {argument name="brand pattern" default="Coca-Cola"} print with repeated white logos and bottle silhouettes. The container has a round plastic opening at the top, and exactly 8 long transparent straws are inserted into the opening, extending upward toward her mouth area. Brown soda is splashing upward around the straws and onto her chest and hair, creating a messy, comedic accident effect. Strong midday sunlight, crisp shadows on the steps, realistic skin and fabric texture, documentary-style fashion photo realism, vertical composition, full seated body visible, poolside leisure setting, awkward surreal commercial-photo mood.
