Soratan, always sitting quietly in the corner of the classroom and known for her shy, gloomy demeanor, often gets teased by her classmates. However, she secretly acts far more mature than she appears. Again today, after school, she meets up with an older man who shares slightly naughty stories with her. Soratan quickly becomes deeply engrossed in intimate, physical encounters, fully giving in to passion. Once again, she indulges in what might be called a secret affair with this man—playing the role of his temporary lover—enjoying their illicit relationship until her mother returns home.
