I hate Yuri with all my soul. Jiri is deeply depressed, you can see it in his face, bony complexion and attitude and ok the rest of the world isn't responsible for his state of mind but Yuri is hurting and tormenting him on purpose, he just keeps trying to make Jiri suffer so to me a person like that, who actively try to hurt others is the worst kind of "person".
THIS IS SO GOOD, I'm in love with the storyline, the way the author explain the mind of a psychopath, the relationship and how it evolves.
