Have you ever started watching something that you knew was going to go bad and the whole time you're just waiting for it to jump off the slope? That is what I felt like when I started reading this. So I kept reading, and reading, and reading. What the hell? Where is the payoff? I felt like Lou from Hot Tub Time Machine waiting for the hotel worker's arm to get hacked off.

You take a straight up yandere girl and put her with a guy that is bland in every since of the word. She wasn't quite up to Yuno standards but she also wasn't involved in a death diary game so basically, Yuno had she not become a mass murderer. Worse like I said before there is no payoff. I was waiting for this to go dark, School Days, style but it never happened. Like people that are obsessed with someone don't have a problem and it is cute. Obsession usually requires therapy as it is a form of addiction but this is played like it is perfectly natural. Hell no! I feel jipped of the yandere explosion moment that this series should've been building up to.

Also on a side note had the genders been reversed and the girl had been stalked by the guy, it probably would have been a thriller/horror story. Just a thought.
