What starts off to look like a romantic comedy turns dreadfully messed up. I stopped after the first 4 episodes because people were saying something about the unexpected ending, so I skipped and watch clips of the final ep... I've never read the manga or anything, so it was a shocker. A dark drama. I've had nightmares about this sort of thing... You can probably suspect what happens based off of the tags listed. (too many spoilers, people!)
Just not my thing. I like my anime either funny, romantic, or action packed. This one started off as something I'd like, but turned to something else altogether.
