This is a really strange manga to describe for me. I feel like I get what they were going for, but I also don't. The core of it seems to be focused on love, parental love, romantic love, etc. of all types and of all combinations. However, its presented in a really strange way, where it's happening randomly and there are a lot of blurred lines that feel really awkward. It was certainly different from anything else I've ever read. The story is primarily about Naoya and Rotte, and that's the relationship that the manga closes on. But the development of that was so strange with her mother and sister and everyoneelse involved and that combined with just the general free tone of the manga made it a very different type of love story I guess. Nothing seems to actually be happening for most of the manga, at least in ways that I can explain, but it's still moving forward sort of. The world itself was pretty generic, though they seemed to focus on aspects different from the ones usually focused on by a large margin which made it somewhat interesting, and the comedy was reasonably solid, though also strange in that it was once again a lot 'freer' for lack of a better word. The art too was decent enough, but it had strange elements to it, especially the framing. Ultimately, I don't particularly feel that it was that good or that bad, rather it was just strange.

tl;dr: A manga about love that is quite strange and unique though maybe not for the better.
