Just finished this manga and it is one hell of a rollercoaster ride and full of frustrations. The author is really good at making you give up yet still keep on clinging just to see the ending. The characters are really unique (like, different rom all the Josei and Shojo manga(s) I've read so far), and I'd say, this is actually wonderfully written. They're very human trying to go and solve their issues in their own way, which took very long and a lot of other stuffs kept coming up and that's why it's frustrating. But I guess, that's how it is in real life.
