I liked the story overall but the ending was probably one of the most unsatisfactory endings I've ever read. It wasn't particularly sad or particularly happy-- it was pretty anticlimactic. I felt like everything got intense and then just... fizzled down. I don't mind endings like this, but it's missing a few elements to it to really be done well in this particular manga.
Liked the story to a certain extent but the ending sucked as hell! I mean, heck, what was the point of all the Furuya x Rea romance if it ended the way it did! I just expected something different, something "good". It's such a shame for such a well-developed manga :(
people are being dramatic about the ending, i thought it was fine. overall it left something to be desired but i really enjoyed the premise and some parts.
