ART: The lines are clean, the style is refreshing, and the emotions are well-portrayed. In short, the art of the manga is very, very good, which is what probably attracted many people to read it in the first place.
PLOT: Unlike the art, the plot of this is nothing particularly special. As has been said, it is very predictable to those familiar with shounen-ai plotlines, so the reader is not kept guessing. Even when a twist is attempted in the end, a few conspicuous comments in earlier chapters let the reader know what will happen. This destroys much of the short series's enjoyability, and it is one of the major weak spots of the manga.
CHARACTERS: Yet again, the familiar faces of shoujo/shounen-ai manga show up: the unsure, emotional main character; the dark, silent, handsome, protective guy; and the equally-handsome, friendly guy. Since the characters are given little if any background, the characterisation for all of them is very weak. These shallow characters do not in any way improve the manga's already stale plotline.
People new to the shounen-ai (or shoujo, for that matter) scene will most likely enjoy this much more than the veterans of the genres. As for the shounen-ai "experts," the story is nothing special, but they might want to watch out for more by this artist simply for her unique and appealing art style.
