My problem was that there was no hint at him being a masochist. Some highschool characters in manga have this "I don't care" attitude towards certain things (like the biting/being bitten) although that could have just been bad writing from the author. So yeah, SOME kind of reaction (blushing, shivering, etc. when bitten) even just a minor one would have been enough to work as a hint. But there was none at all so it's quite badly written and/or executed in the final work.
I have 10+ years of experience with manga, so I can see even the smallest hints, but even in the worst manga I have read there was at least some kind of reaction from the masochist/submissive person when someone did/said something sadistic or dominant to them. There was nothing of sorts in this manga, hence my disappointment. Especially since the art is so extremely good.

Yeah, well I tend to be much more strict with manga that have good artworks. I'm the same as you, bad art hurts my eyes whereas good at can make up for a bad story. :'D
But this manga couldn't really save itself with the art (for me personally. It would have needed Akira Norikazu type of artwork...which it's far from having XD).
I have probably too much experience with manga (good ones especially) to give this one a better rating. And I generally give them an overall score, not seperate ones for art, story and characters or such. I'd give it the 5/10 for artwork too tho. I can fully agree on that. ( ouo)b
Ok, it seemed really random that the main character suddenly turned into a masochist (I say turned into, but he was probably supposed to be one from the start...which he wasn't so..). You know, just like *snips finger* that. There was not a single indication for that. Not even a little. wth. X'D
Anyways, good art. Story is indeed 'meh' because of the randomness and the kinda forced "he has a tragic backstory that's why he behaves this way" stuff just to get to the sm sexy times.
I like BDSM/SM plots, but this one is pretty bad based on plot and characters, so I'd definitely not recommend it.
2/3 outta 10, mainly for the art and not fucked-up-ness tho.
