It's so beautiful yet disturbing, but intriguing all at once. Read this multiple times. I can still remember my first time reading this. It was a very complex emotional journey. One of my absolute favorite parts of this manga is the connection all the characters play. From main to side characters. All of them make you so invested. Readers should be warned though that it is very dark. Proceed with caution .
