I saw the first episode last night, actually! ^.^
It's way better than I thought it was going to be... I was a bit hesitant about watching, but I actually really like it!
The characters are very well fleshed out. They have history, quirks, mannerisms and other things that make them seem a lot more personal than just an anime character.
And it is a bit of a suspense as well as drama... It's very well done. :3
