This one is pretty good for people, who start their adventure's with Yuki-sensei work. The art is amazing like always - dark, stunning, marvellous, but not so gloomy as it can be in her other mangas. It's lighter, but not light and it's really big plus.
The same goes for story - we have some difficult cases and perfumer, who more or less unwillingly play the role of detective. The main hero and heroine are really nicely done. They aren't clones of billions manga characters, but people of flash and blood. The story wouldn't be so interesting if not for them. What's important, the reader can really like them, remember them and there isn't any dark in them. Yuki-sensei likes controversies, but she somewhat make that one easier for reader, and I really liked it. It's really a pity that this manga is so short.
The biggest both advantage and disadvantage is that it was made by Kaori Yuki. I'm great fan of her, but once again she repeated the same thing's which I didn't like. It's too short, many things aren't explained, they leave us with too many questions and sometimes the story is so complicated, that it becomes unrealistic. I still love it, but really - if she does something so crazy, she should make it longer.
The only thing I didn't like and it wasn't characteristic for Yuki-sensei, was that hero's sense of scent was praised this much in such a short manga, but it's wasn't really that annoying as I thought it would be.
