This manga was so great that I hated it by chapter 2, but I kept reading anyway, and you know, I got an even greater love for this manga the more I read. Things happen, then more things happen, then things that happened before are just kinda dropped or lead to anti-climax, then you wonder why they happened in the first place, then it's over. It's great.
With story-telling that falls flat, characters that are all uninteresting assholes, an unfulfilling ending, and foreshadowing that's on the level of the girl protagonist wearing a shirt that says, "You will love him", what's not to absolutely love?
Being more serious, this manga tries to tell a story it itself finds interesting, and tries to convey messages, but it all falls pathetically flat upon execution. Virtually all of its messages were hand-fisted, and in one case that came out of no-where, it felt like the author took one of the themes they wanted to get to in the story but couldn't find an appropriate place to write it in at, put it into a potato sack and just slammed it into the back of the reader's head over and over; "Hey, this is a pretty clever thing I'm trying to make a point of, right?!"
The art is okayy, the paneling isn't terrible except for a few points where I had to go ahead a couple panels before understanding what the hell was trying to be conveyed a couple panels before, and the pretentiousness is arguably high.
There's no reason to read this manga. Unless you want to look at two 15-year-olds going at it or feel as unfulfilled as two actual 15-year-olds going at it, don't go near this.
