tl;dr: A lighthearted and cute manga filled with a series of short stories about various children in a kindergarten and their teachers. This manga is really cute and amusing. It composed of a bunch of small stories without any major plot threads or character arcs. These stories feature the same characters and setting so obviously a lot of elements do carry through out, but these are generally just the basis for or in the background of the stories, and in general it’s not like the stories in the manga actually progress any of these elements. Rather, for the most part, where things are when a characteris introduced is how things stay throughout. Now that's not to say that the stories don’t have any depth, this is a manga featuring little kids so a lot of the time there would be some sort of moral they learn at the end of each story. There were also a lot of stories that while not really advancing things did help better flesh out what was already there. And also, while no overarching progress was the standard, there was a major exception which did have some progress, though really slow progress, throughout, and that the ending focused on for a reasonably satisfying conclusion. Really though, all of that’s just icing on the cake in that what really makes the substance of the manga is that it’s really cute and amusing. It’s not hilarious in that it’ll have you laughing a lot, but the adorable humor is enough to keep you smiling throughout. Furthermore, I thought it did a good job with variety and such, in that it even though from afar it looks like its repeatedly dealing with the same subject matter regarding how children behave throughout, it never felt like it was dragging on and always felt pretty well paced. The art was also pretty solid in that it was quite cute and fitting the subject matter, and I also think it improved quite a bit from around the third volume or so.
