I agree with the fact that the story is disgusting with the topics mentioned, however I disagree with wanting Sangwoo and Bum to be together. Their relationship is 110% fucked up, and that's what the story is! I enjoy this story because it is interesting, not because I ship them. This is clearly a fucked up story, so if you are sensitive to stuff like this then just don't read it?
i've cried so much because of this manga. I adore it, and i've seen all these people grow up (especially the twins) and i can't even explain how much i love this story but... I wish there was some more. I'm glad that we got to see them get together but I really wished that we could see their story past this, like if they got married, lived together, if they would take the twins,,, but it's alright. I love this manga and I give much thanks to the author and those who helped bring the manga here.
