The flow of the story line was pretty cliche and shoujo-esk. Hot, negatively rumored guy looks for shy unknown girl, or in this case a guy. bad guy turns out good, relationship goes well and stuff. the only thing it missed to be pin point shoujo cliche is a misunderstanding of sorts. Also the atmosphere and lack of depth in the characters adds to the shoujo cliche.
Actually I think it's cause there wasn't a misunderstanding that it seems like a shojo cause in the few straight love mangas I've read there wasn't a misunderstanding. And I've seen this kinda setting before in yaoi (that the hot delinquent who is misunderstood falls for either the shy guy in class, mr. popular, or the cute guy)
I'm not really sure what to make of this :/ It was a really good yaoi. It's the only yaoi that I've read that had a cliche shojo romance feel to it and that made it really cute and unique :D But the thing is, I have no idea what it is that makes it feel like a cliche shojo romance manga
