I loved it. Warning: This manga is not translated from the end of chapter 65 onward to 77 but there are blogs that talk about what happens, and it's a happy ending. Now I'll review:

I personally love the art, aside from the hands at times (the fingers can be a bit too long). It's unique, and it's refreshing. A lot of people critic the art, but as I like it I'm giving it a 9.

Characters are great, the romance wasn't a instant love like most other manga out there, it was paced over the 77 chapters and the love confession doesn't come until almost the end of the manga. That said, the romance is still there in small bits, enough to make you get all excited when it does happen. And you know fairly early on who she'll end up with, like most manga out there.
They could have been more developed, I would have loved to see the past of some more characters and get more in depth but honestly it wasn't a huge deal to me, it was a fun read.

I enjoyed it a lot, I read it all in one sitting.
