Yeah, you can tell this was her/his first story. I like this mangaka's typical approach to dark humor and the sinister feeling underlying the other stories. This one was just clumsy and obvious. It was kind of funny, just the way that the characters start off, but nothing was ever explained, and there was nothing original here. Bummer. I wouldn't start with this one if you want to enjoy this author, though I have to say that most of the work is for those who appreciate the morose beneath the seemingly cheerful and innocent.
