Tomo Aizawa is very much a tomboy. She is also in love with Junichiro, a boy she has been friends with since childhood. One day she plucks up the courage to tell him but he misunderstands, it doesn't cross his mind that she meant it romantically rather than as friends. She persists in trying to get him to see her as more than just a friend but things never seem to go her way.
I thought this series was a lot of fun. There are plenty of laughs to be had in every episode. The characters are solid, as well as Tomo and Junichiro there is Misuzu, Tomo's sadistic friend and Carol, a bubbly girl of British ancestry. The character designs are good; I like the fact that Tomo is in no way androgynous; so the fact that she is a girl isn't disputed, it is just her tomboyish behaviour. Overall a really fun series that I'd certainly recommend to any anime fan looking for a good laugh.
