Asako is a dreamy 17-year-old schoolgirl who is disillusioned with the mendacity of study and her impending exams. Gradually she retreats from school and the world around her and begins to hide out at home, unbeknownst to her divorced mother.
Then, one day, in an effort to make a fresh start, she shifts all her personal belongings from her room to the garbage disposal area of her apartment building. There she meets Kazuyoshi, a preternaturally intelligent 10-year-old boy who politely asks if he may have her obsolete computer.
Soon he makes Asako an offer she can't refuse - "why not join forces with me and work together?" Much to her surprise she discovers that, tucked away from prying eyes in a closet in his bedroom, Kazuyoshi has been running an erotic internet chat business on behalf of a married siren named "Miyabi."
At first, Asako proves as inexperienced at operating a computer as she is at dealing with the lascivious advances of the opposite sex, but her curiosity propels her ever onward into an exhilarating adult world that she never knew existed.
The strange new sensations Asako experiences open her to a realm of unforeseen possibilities, but just how far is she willing to go?
