I enjoy this manwha. It's one of my favorites in the psychological horror genre. The ending did sadden me but not for Sang-woo of course he had what was coming for him. But for Yoonbum, I wish that he would have a good ending where he was loved and cared for but that's just wishful thinking. It annoys me how so many people call this a romance and that they excuse the actions of sang-woo because "bad things happen to him and that he is just a sad boy" Like what the hell. This manwha is no way a romance or something to idolize after. It's a horror, thriller, psychological one and should be treated as such.
