This manga is incorectly tagged as BL all over the internet. This is NOT BL!!! People, wake the fuck up, stop cosplaying and stop romanticizing a clearly twisted and disturbing psycological study of trauma and violence !!!!!!
This is a very good story, but only if you look at it from the right angle. There is no love here. Only obsession, stalking, violence and extreme trauma. The author keeps explaining this again and again and people are just fucked up.
Stop making this series into something that it is not. And, to any Anime Planet moderators - please, please, please remove the BL tag. This is actually the reason I started reading this manga and was absolutely shocked to realize it's a completely different monster. Too bad though, because this manga is a psycological masterpiece, but it isn't getting the appreciation it deserves.
