The manga has an interesting premise and the art is nice enough, but overall, I was underwhelmed by the story. Given its solid first chapter, I wanted to like this manga more, but unfortunately, there were so many gaps in the plot development that I couldn't fully enjoy the story as I'd wanted to.
In many ways, this manga feels like reading a disorganized summary of a longer manga rather than reading the manga itself. For example, the revelation of the mysterious past incident that drove Kazuki out of his home seems to come out of nowhere as we knew very little about the characters or their relationships with one another prior to that, which was crucial for understanding why/how things turned out as they did. What little explaination the manga does give is quickly rushed through and readers are left to guess about what's left out--namely, the exact nature of the relationship between Moriyasu and Kazuki prior to the incident (were they friends as well? Did they only see one another because of Kazuki's brother?) In general, the exact relationship between Moriyasu, Kazuki, and Kazuki's bother is never adequately explained (which was a VERY important part of the overall story). Not only flashback information, but also present-day events are poorly developed as Kazuki's transformation from streetwise kid to housewife, for instance, is way too sudden to be believable. Why exactly Kazuki ended up the way that he did is also ignored--couldn't he get a job? Didn't he want one?
Besides the main story, the two other oneshots that comprise the volume also feel as though they should've been longer, the plot and characters developed more. Overall, this manga doesn't leave me with a good impression of the mangaka's storytelling abilities or encourage me to seek out more of her works.
