fucking masterpiece, undoubtedly
The most my emotions have fluctuated in such a short time period, yet in only 20 so chapters you become so emotionally attached to any character in the story, and you feel the punch when one meets their own demise.
If you've read Aku no Hana u should know how good it is being one of the other few mangas I rate a 10 this is completely on par with the characters, depth, plot, and just everything it's so amazing.
The only flaw personally I can really think of is that, I wish it was just longer, I wanted it to keep going, yet I'm satisfied with its ending I wish it wouldn't end. hell I wouldn't be mad it this had 1,000 chapters, it would be completely worth the read at any length.
I can't recommend it enough
