Really liked this manga, and it was really engrossing. It was melodramatic at times, and frankly, I don't think Akitsuki is such a stud that he could get all those girls lusting after him in real life, but there was just so much depth in Akitsuki's character that I could completely forgive the fact that Suzuka was not really developed at all. Which is fine, because this is all his perspective anyway, so you really don't get very much of what Suzuka's thinking and both he and the reader just have to guess. I especially liked how the internal monologues of him thinking, "I'm fine just being friends, I don't have to go any further than this," while his mouth is saying, "I wanna go out with you", which shows how much he's trying to trick himself into taking the easy way, and he just can't.
Of course I probably wouldn't have been interested nearly long enough to be hooked if the boobies weren't shown constantly in the first couple books, but the author knew what he was doing, and the boobies were really there just to keep you interested till the story picked up and slowly and subtly they're shown less and less, till you get to the last chapters and theres no boobs at all, and you really could care less.
And I liked the ending. Sure the whole thing was rushed, and its obvious the author wanted to wrap it up as soon as possible, but it seems to me, and its entirely possible I'm reading too much into this, that the ending was a symbol of whether they value track more than each other. Not a very good symbol because they can conceivably still have a healthy relationship even if they did choose track, but the fact that they unanimously chose giving up track for the sake of one another was definitely a good way to end it.
