Well, when I read first chapter, I was like "wtf 8.5/10 for this shit of hentai", weeeeeell I wasn't right, it's just a psychopath story.
Here we go with the story. Well average guy with no friends takes up-skirt photos to escape reality, when he's fund out by a psycho-girl who likes bonding (rope and stuff) people. At least it's original.
Well art is quite good. Nothing to say, it's better than average.
Characters, nothing new except for the bonding part. An average pervert and a Yandere, well kinda bad.
Enjoyment ? Well tell me if someone ever had fun reading this, it's just bad, in the very least
sad and depressive.
Overall 5/10 (thanks to the art, otherwise it would be 4/10). Honestly don't read this. There are much better psychopaths stories, really.
