To be quite honest, I think the only really good part of this manga is the art. However even so the talking bubbles can be confusing and all the characters are too "undeniably beautiful". It's a beautiful style but just having good art isn't enough.

It's boring. I'll admit at first I thought I was curious and found it interesting. But over time, the repitiveness becomes annoying and irritating. It seems as if the same three main characters of this manga receive too much attention while all the others, who are probably even better than the main protagonists, receives a very minimum screentime. (Or linetime, w/e)

Yuuki, the main protagonists whom apparently the whole world revolves around, is your typical girl in a romantic story. There's nothing special about her whatsoever.

As for enjoyment... the odd love triangles in this story are appalling. There is much... incest and the story itself is confusing at points. I also think that the author, Matsuri Hino, is merely beating around the bush and isn't getting straight forward to the important parts in the story. I think in her attempts to lengthen the manga, she is just adding in bits of boring panels.
