I have a problem with this drama. Look, I loved the concept but one thing that falls apart is the very thing this series is revolving in: Nanno. Nanno is omniscient which makes everything so predictable. The only thing the omniscient Nanno was executed properly was on episode 2 which kind of needed Nanno to be omniscient. But as for everything else, I would have preferred it to have another leading character except for Nanno. Having Nanno makes everything so predictable, and instead of it being a mystery, this seems more like a documentary. Also, there are times that Nanno feels very... odd. She feels very different each episode, very inconsistent. I mean that could be a style, but I would have liked it better if each episode focused on a different girl character but with the same actress.

The concept of Nanno is so flawed that I would have wished her to be gone instead. *Sigh*
