It's a slice of life very short. Absolutely nothing is going to be explained about why the things that happen happen, or anything about the characters, but that's fine. The story is the least important of all. However, it is entertaining, and it is good to disconnect from the complex plots that require a lot of attention. It is practically a job done to demonstrate the animation capabilities of a studio, or at least that's how I see it, despite the fact that it has already produced several animes. I think that each episode changes the opening, which lasts more or less 30 seconds; Inthat aspect you will not be so bored.
Honestly, it made me much funnier than other "comedy" anime out there.
