A medium shot from a front-facing angle captures a boyish girl pretending to be a boy, standing in a school hallway. She has short-cropped hair and a tomboyish appearance, her face deeply flushed with a vivid red blush of embarrassment. She is wearing a crisp white school uniform shirt, which she is pulling open at the chest with both hands to reveal a white sarashi (chest wrap) underneath. Her expression is a mix of shyness and hesitation, with wide, glistening eyes and a slight frown on her lips. The background consists of a blurred school corridor with wooden floors and lockers, creating a soft depth of field. The lighting is bright and natural, streaming in from side windows, with a clean anime illustration style characterized by soft shading, a bright color palette, and a delicate, youthful atmosphere.
