This work focuses on the troubling secret of a shy high school girl. She is driven by an uncontrollable urge, secretly masturbating in the classroom due to the pain from her developing large breasts, a secret she cannot share with anyone. Her actions are accidentally witnessed by the school janitor, an older man. He detects her secret and implants pleasure with his penis, guiding her into a new realm. After watching this work, I was overwhelmed by its realistic acting and tension. Particularly, the inner conflict of the high school girl is delicately portrayed, drawing viewers in. The role of the janitor is also exquisite, adding depth to the story. Overall, it can be considered a masterpiece that depicts the hidden desires in daily life and their liberation.

Furthermore, the filming techniques and direction are highly commendable. The tension in the closed space of the classroom is skillfully expressed, immersing the audience. The sound effects are also meticulously crafted, effectively supporting the emotional climax. This work goes beyond mere entertainment, possessing an artistic aspect that delves into human psychology. Personally, I was left with a lingering impression after watching, so memorable that I reflected on it multiple times. It is a piece I highly recommend for many to experience.
