This truly demonstrated that not every story can have a happy ending, it's still very depressing to think of what Saki's life could've been. One of the things that hit me the hardest about this manga was the fact that this is a very real situation, that something like this could be happening in the world right this moment. Metamorphosis was truly a beautiful yet tragic tale, at first I was a bit skeptical due it being a hentai, but soon enough I found myself completely immersed in the manga, all my doubts washing away, sexuality and sex in general is used to represent Saki falling deeper and deeper into a hole, it's extremely creative and executed very well on top of that. The manga ends with a final panel of the broken glasses laying on the floor with Saki's blood surrounding it.
