In all honesty, i didn't get this anime at all. It's like some kind of reverse harem with some strange characters that i don't get at all. what i really don't get is why was this anime labeled seinen...it doesn't make sense, it doesn't deserve the spot and seinen audience.
The characters are weird, more than half of the cast is male (What the hell?) and weird ones at that, most male characters are completely weird, except for the main character. all kinds of strange guys are thrown in this anime, a doctor who dresses weird, i'm not sure even if the clothes he's wearing are for men. you got an either very feminine guy or a girl in denial, a masochist one for that matter, you've got a...i dunno what to say, this anime doesn't make sense, the plot doesn't make sense, the characters don't make sense, i don't know who the hell are these stupid animators who decided to adapt the manga to an anime, it's a waste of space.
basically if you're looking for a good action/romance anime (Because that's what most people thought before watching it), then this anime is not for you, but if you're the person who likes weird stuff and weird characters and plots that don't make sense, then by all means, go for it.
