## Plot

Shigeta, a young woman of 24, spends her days working at Tanaka Books and fretting over her love-life; or, more accurately, the lack thereof. The thing is, though, the biggest obstacle between Shigeta and a satisfying relationship seems to be Shigeta herself. When it comes to men, the poor girl has exceedingly poor judgement, exacerbated by her even poorer self-esteem.

## Characters
### Kayoko Shigeta (重田 加代子, Shigeta Kayoko)

    Kayoko is an insecure 24-year-old woman who is quick to fall for potential suitors and even quicker to draw conclusions about those who she perceives as threatening to her love life.

### Shuichi Takahashi (高橋 修一, Takahashi Shūichi)

    A worker at the same bookstore as Kayoko. Shuichi is a student at Tokyo University and is in love with Kayoko despite her constant exploits with other men.

### Hiromi Fukunaga (福永 ヒロミ, Fukunaga Hiromi) / Fuku (フクちゃん, Fuku-chan)

    Shigeta's roommate and best friend. Fuku is a slightly older and significantly more grounded female character in the story whose relative success with men and more laid back demeanor serve as useful contrasts to Kayoko.

### Yuko Tanabe

    Another worker at the bookstore, Yuko is a plain looking girl who Kayoko is angered by when she finds out that Yuko has a boyfriend. Kayoko jealously seduces Yuko's boyfriend and has sex with him in a car but is then disappointed to find out that he is not, in fact, in love with her.

### Tokieda (時枝)

    A hip DJ that Kayoko meets in a club, Toki is the most significant crush that Kayoko has. After things do not work out with him, Kayoko temporarily renounces boys and focuses on work.

### Kunihiko Sakai (境 邦彦, Sakai Kunihiko)

    The son of a cult leader who Kayoko meets in her hometown when visiting her mother to borrow money. He stalks her after her interest in him wanes leading to his kidnap and near-rape of her, before Shuichi saves her.

### Violet

    Violet is a student. When Kayoko sees that Violet is interested in Shuichi, she too realizes his worth as a suitor and gets together with him.

### Goro Kishiwada (岸和田 悟郎, Kishiwada Gorō)

    Kishiwada is another of Kayoko's lovers. An accomplished pottery artist, Kishiwada is the reason that Kayoko takes a job as an apprentice to a pottery teacher.

### Miss Midori

    A rumored nymphomaniac, Miss Midori is Kishiwada's lover, and runs away with him.
