I dont know.
It started off amazing and then... the author's going for some kind of thriller shenanigans, but his characters dont make any sense at all. The main character's supposed to be a coward, but he shows extreme courage and wits in do or die situations. His new GF is supposed to be a regular woman, but she too shows extreme courage and resilience. Also, why is she so infutuated with him? All of this might be explained later on, but i find it all odd and it makes the story hard to enjoy. Also the goth-girl is extremely annoying.
The dialogues are a tad off too, but it could be the translation.
I'd have rather had a Hangover type of story where the main character's looking for the clues as to how he got there in the first place and the story focuses on that, instead of that weird mish-mash between body horror, thriller and third-rate romance. It's some kind of mix between Dr Jekyll and Mr Hide, a B Horror movie, and an ecchi.
Right now, i do not feel any tension. I got shivers in the first few chapters but now it's all gone because it's all too unbelievable.
Well, at least the author chose not to go the obvious way, which is commendable.
I wont rate it yet, i'd rather wait for what's coming. But honestly, seeing how the story has devolved... i've my doubts.
