If you are wondering about whether to pick it up or not, I'll say only three words, "JUST READ IT". Yes it is that good. This story is something to be experienced. Don't be mislead by horror or other tags. Just go with it. It'll give you all kinds of feels you can imagine and then just will leave you heartbroken. And just after that it'll give you a consolation to ease the pain. Although I wanted it to be a small review but unfortunately Mal won't let me, so I'll give more teases about the Manga. The story is well paced and is brilliantly distributed amongthe volumes. It doest feels rushed or slow paced. Characters are well devolped and are not half assed.
The story moves with intent and with a clear direction and concludes with a decent conclusion.
So you, yes you, who's reading this review. Do us all a favour by stop wasting your time and start reading it XD
