This is a "Girl's Diary" of four very different girls' lives recorded in four short stories.
1. The O Girl
She tells him that they'll start as "just friends" but he seems to feel differently, telling her that she can't cheat on him?!
2. The S Girl
Always acting as the servant of the guy she likes, Rei-chan is starting to get fed up with this lifestyle.
3. The Girl in the Legend
Just as Tanoko has decided her fate as being only remembered for dying at her school, she meets the most popular guy, who seems to have a problem with being alone...
4. The Negative Girl
All the guys Hinako has dated have ended up in accidents, their lives being almost completely ruined while being with her. Hinako believes that her so-called "negative aura" isn't just coincidence.
