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.
