Probably from people who got annoyed back when it used to be stuck at ch4
Well but I don't think that's a reason to rate a work negatively, that's something that doesn't concern the story itself... I mean, it's not the manga's fault if whoever was posting/translating it in english suddenly dropped it... Besides, there are several manga that were dropped after a few chapters and have a high rating! I think it could be for the reasons I mentioned at the end of my first comment...
I genuinely wonder why this manga is only rated 9.0? I mean, by the standards of this site it's not much... Imo the plot is quite original and totally intriguing, the characters are enigmatic and interesting, and the art is beautiful... I think it's a shame because I've seen manga with the most trivial and predictable clichés and characters rated 9.4/5/6, maybe because they're all cuteness and fluff but damn, are they boring
I noticed this in the context of yaoi, unfortunately I think there's a tendency to rate something lower just because the story has dark elements, heavier themes or the characters are not the classic "ideal" type...
