Despite the front cover and especially the back cover, there is no sex in this and naught but one page with nudity (It's an artists drawing at the end of Kotori). The main story itself is of Jyunichi telling Nemu and Sakura (at different times) a fairy tale... It seems almost like the story of them, and it's a pretty emotional story.

Despite the first drawing (sans cover) being of Kotori, she doesnt appear in the actual storyline doujin.

Art: The art is well done in some places and bad in others. The girls are drawn superbly. The cover images and the stills of Kotori and the others at the end are magnificent. During the doujin, most of the time the art is good. This goes for everything except Jyunichi. He wasnt drawn very well at all...

Story: It's cute. I already noted this one. Full marks. Read it. If you cant, get it translated.

Overall: Read it if you can. If not, look at the still images. They're really pretty.
