Think of the worst things that can happen. It happens here. Not only that, but this manga takes the phrase 'from bad to worse' to a whole new level. Wow. I don't think I've ever read anything that rips out my heart like this manga.
Story: Like above. Wow. Just wow. Have tissues, and maybe someone to talk to about your feelings after this one, because just when you thought something good will happen- NOPE! But dagnabit, I want them to end up happy! So if that was the intent, well done.
Art: Didn't really do it for me. There was more than a few panels that were awkward. Maybe it might be your cup of tea, but not quite mine.
Character: They were, despite every horrible thing that happened, somewhat believable. I understood their motivations and wanted them to succeed, and there was a good deal of growth. Well done.
Overall- This plays out like some of Law and Order SVU, and it is a good read if you want a good cry. This novel is a good one, but very heavy. Worth a read, but not exactly a top priority. Just remember to talk to Olivia Benson about your emotions afterwards and hug a stuffed animal or something.
