Yeah, Sangwoo and Bum, they're bad for each other, but they aren't good for anyone else. And the cop, he isn't completely normal either.
you basically summarize all this manhwa! good job ^_^ it all very simple - all the characters in this manhwa is fuck up, that could be evoided if only their fuck up perents would take care of them like they should and give them some love! but well, I think Bum which some help could have been better by himself. but then again he got obsessive on the "love of his life" so...yeas XD
Everyone is trying to choose sides with Bum, Sangwoo and the cop. Can't y'all see everyone is pretty fucked up in their own way? The cops being assholes who can't seem to help eachother and see eye to eye. Which is why the cop is in the position he is in. Bum had a fucked up life, has no one to rely on and was hurt by those he called family. It's why he's tried to kill himself. It might seem dumb to some people why he stays with Sangwoo, but perhaps it's because even if the situation is fucked up he's not alone. Sangwoo is just completely fucked in the head but how did he get there? I think they stick to eachother because they know they're both mentally screwed and know no one would want to be with someone like them. Everyone in the manga is really messed up and that's why everything is ending up the way it is.
K, rant is over
