It is Aoi’s seventeenth birthday. She has been raped by her friends and deeply shocked. She turns to her family for support and comfort only to be rejected. She decides to do away with herself and is about to jump from the roof of the school building, when she receives an e-mail message on her cell phone. It was a wrong number, but she finds consolation in the message and decides not to kill herself. However, she cannot bring herself to go back home and wanders the streets. She is picked up by Kanai who was scouting around for girls, and begins to work at a bar as a hostess, calling herself “Ai.” She starts selling herself and encounters Ishikawa, a shady character who spends a lot of money in a reckless way. Ai leads a day-to-day existence for money with Akemi, the most popular hostess at the bar. Her sole consolation was in exchanging e-mail messages with Toshi, the one who had sent her that e-mail by mistake. Ai does not tell him how she makes a living, but comes to love him, and moves in with him. However, the production of the five pornographic videos, which she had agreed to do in exchange for five million yen, had already begun by then.
