Kiyohara Hiro´s art is beautiful, as usual... but there are other stories by Otsu-Ichi that I liked better. The main problem is the ending... I would have chopped off most of the fourth chapter, which is too explanatory. I think there was no need to give so much explanation, most of what is explained there is already clear by the end of the previous chapter... so unnecessary.
But the idea was good, the characters are interesting (given the length of the manga), and the art is really nice.
