I can honestly say that this story has been the most gory and thrilling manga I've ever read. I can understand the psychotic nature (because with parents like those, who wouldn't?). I love that he was willing to do anything for his hyung. I was disappointed that it didn't have BL even though it showed in the tags it wouldn't, but a girl can dream. So, honestly if you like gore, psychotic people, suspense and all around traumatizing stuff. This is for you.
