its up to us to decide if he died or not but the ending implies that he did...
his mom never wanted him to begin with. she tried to murder her child, then her husband stopped her but he (her husband) started to feel disgusted by her. after, he started beating her and sangwoo ended up killing his dad. his mother had a weird affection towards sangwoo so thats why she was asked him to come to her room while she was fking with another man (and then sangwoo did the same with bum lol). after the death of his father his mother started to think of sangwoo as his dad (he was the replacement of his dad) so she gave him some pills in order to fk or smth. then sungwoo realizes that and he kills her but since she is his mother, the line between disgust, hate and love is really thin so he starts having some sorts of feelings for her. he starts killing women because he believes that all women are bad and he tries not to get to intimate with them. but then bum comes, who is not a woman but he somehow resembles his mother so sangwoo starts doing to bum what his mother did to him... and he(sangwoo) keeps her(his mother) close to him because he thinks she is precious in some way..
the policeman was suprised due to the fact that unlike the other bodies, his mother was untouched and was put in a weird position like she was watching over him.
Well, Sangwoo didn't kill his father. His mom did then she made it like Sangwoo's the one who murdered the father and I think the pills are poisonous so his mother was probably trying to kill him the same way she killed his father. Not to fuck so he was terrified to think he would die the same way his father did.
after some chapters he says that he did kill him but tried to hide it from himself(in order not to blame himseld) so we cant be sure. but ofc his mother was the cause for this...
and his mother wanted to have sex with him, there were hints before the killing part that imply that "babe".
the pills were supposed to eventually kill him but there was no clue about what the pills were but they seem like sleeping pills to me.
Honey, Sangwoo did not kill his father, or his mother. His mother poisoned his father with the pills (it is speculated that it was actually rat poison in tablet form and she had been poisoning him for some time which may have actually led to him becoming violent with her as the poison was messing with his brain.) His mother hated Sangwoo because he looked like his father and because she didn't want a child, she tried to abort him, tried to smother him with a pillow when he was a toddler, tried to poison him the same way she did his father, she had no sexual attraction towards him, she used sex to break his spirit, she even says to him before raping him ''do you know the way to kill someone without killing them?'' or something to that effect and then rapes him. She stabs herself in the neck with the knife Sangwoo was holding in order to fend her off. Sangwoo thinks himself as the killer of his parents because he is delusional from his trauma, he hallucinates his mother all around the house, you can't really take his words at face value. You should probably read it from the beginning. :)
thank god i didn't waste time reading finish. gave up after 10 chaps
Spoilers Ahead
I don't really get the ending???? Like does Bum die??
