Well... the ending threw me off. To the point I don't remember what the previous chapters were like. It's not exactly the first time it happened, side effect when your not reading things in one go and reading a whole bunch of different mangas at the same time.
I'll say this though, the ending was a huge disappointment. Didn't really get what's going on, then boom! Last chapter. Specificately saying, the last two chapters. Before that I was still following.
Story... is probably decent? Not the best, but I don't remember it being too horrible. Can't say more, like I said, don't remember. As for art, I'd say it pretty good. Honestly, I can tell horrible from average and from absolutely amazing, but as for the rest that fall in between the middle, I dunno what else to describe them ><. So yea, not the best, not the greatest, but definitely not bad. I'll say as much as it's not my fav style though, the kind of shoujo art leaning a bit towards baby faces.
In any case, worth reading, now that it's finished. But I honestly think you won't be satisfied when you finish reading. All depends, if you think you can survive reading average or perhaps a bit above mangas, or you really don't care and wants a time spender, go ahead. I won't recommend it that much myself, leaves a bad taste in your mouth.
