Without a linear storyline, the anime works its script through jokes.
Basically the plot works around the interaction of the characters and their stereotypes, making unfunny jokes with that.
Talking a little bit about the characters... They are simple scripting features, which follow to the letter their sterilotypes.
Briefly the pace of the series is slow to the point of not presenting any proposals to the viewer and when he presents a proposal to the viewer, such as romance, he has no idea what he is doing.
