To repay her boyfriend's debt, a G-cup school girl is forced to provide physical services using her young body. Unaware of the full extent of her situation, she falls victim to sexual exploitation by loan collectors. She is repeatedly subjected to various abuses, including forced blowjob, selling her underwear, and engaging in paid sex. In the end, she gets creampied by a homeless-looking man. Her lifeless line, "How much do I still owe...?" powerfully reflects the harsh reality faced by today's teenage girls, giving the story a uniquely compelling charm.
