This manga will grab your heart and toss it around like a stuffed toy from start to finish. It is simply AMAZING, it is really sad and kinda disturbing, but that is part of what makes it so amazing. It has a very refreshing way of telling a cheating story. There's not a clear "villlan" here, it is a story of manipulation, selfishness and love that everyone can "enjoy" (You'll enjoy it, of course, but you will also suffer with the characters). If you're not up to feeling sad and angry while reading... I would still recommend this to you, because it is really well written, reallywell paced and has amazing art.
It is, overal, a masterpiece.
Hope it continues beign this amazing in the future
