Just finished reading up to chapter 43.. And my opinion at the moment is that this manga is overrated. I'm not saying It's a bad story, It's just that It has a couple major flaws. :x
Firstly, the most evident problem in my opinion, and also what bothered me the most, is that at some point the story became too convenient for the MC, what made him become arrogant and ultimately lead to the events that happened on the chapters 29 to 32. Events which made me get close to hating the MC for his childish and selfish behaviour. :s
Secondly, I found It to be annoying the way that sometimes the author just keeps adding things to the story without giving the readers enough information for us to diggest what is happening.
It felt like he was pulling things out of his ass and just stuffing those into the story, hoping that It would turn out ok. :u
...
Anyways, I just frankly hope that the author is done screwing up things, and that he somehow fix the messes he did. Because, despite the things I pointed out, I mostly enjoyed reading this story.
And my advice to the people that are interested in this manga is that.. They should read It and form their own opinions. :b
