I started reading it because of the artwork.
It's really great! You enjoy from the start to finish and being a 2015 manga, you see it is really something.
I had a lovely emotional experience with the story. I cried for a while when I was reading the last chapters when hit the darkest moment in the story.
But I do think storyline didn't have the same quality as the rest.
A big part of the story is consumed... maybe half is consumed by the saddest moments of the story.
And the ending seemed a bit messy. It seems it was done a bit in a rush...
Overall, even about a taboo love story, I do recommend it.
