A girl in a sailor uniform walks through the cold air, her breath visible in the frosty winter silence blanketed by snow, resembling a silver world. She smiles shyly, maintaining her serious nature. Though her grades slipped when she first entered ●● High, she never got into trouble. She loves kissing—her first experience was at ■■ years old. From that trembling moment on, she became aware of romance. At ★★ years old, she lost her virginity, overwhelmed by passion. Disliking school, she once impulsively locked herself in her boyfriend's house for three days—an act of quiet rebellion. Now, as an adult, she bares herself to the camera, reminiscing about her days at ●● High.
