I know I thought exactly like you when I started reading this manhwa I would get so angry when I read those people who ship them in the beginning, romanticizing the abuse, murder, the wounds, etc. But now after this last chapters that we know the true I can't help but sympathize with him, I mean yes he does need psychiatric help but all of his actions were consequence of his fucking mother I can't blame him for those murders I mean that was all of his mother doing, Sangwoo's life would've been so different if it wasn't for her. I feel so bad for him. It's not okay tho but i'll like them to start living like normal people to start a new life without all of those murders and traumas

I was sarcastic, I hate Sangwoo and I'm sincerely bothered by all the justifications he's getting just because he suffered :P tbh even though i think he didn't deserve the abuse (obviously), I can't feel pity for him. He tortured (maybe) raped and killed innocent girls, and the same he did for Bum. I was joking because OP is afraid the "poor guy" will break up if Bum doesn't understand him, but the "poor guy" was the reason Bum attempted suicide in chapter 26.

Of course Sangwoo is a pysopathic murderer who mistreated Bum, but don't just write Bum off as a victim, he's murdered and helped cover Sangwoos up too. But with the latest chapters explaining what made Sangwoo a serial killer one can't help but sympathize, when i say i want bum to treat his out burst with kindness, i want him to because a harsh reaction to his trauma will most likely send him in a murderous rage. He's already been abused enough, he needs help but that requires the right treatment.

I'm sure Bum will understand Sangwoo, unless Koogi wants to make him out of character.
And yes Bum killed and covered Sangwoo up, but who forced him in that situation? Also, Bum covering him up means he's grateful of the good things sangwoo did for him. Maybe it's just his mental illness, but he easily forgives Sangwoo even though he raped, humiliated and tortured him so i think he will comfort him if Sangwoo tells him the truth.
I feel so bad for sangwoo he definitely has trauma. I think its safe to say from the look on his face after he called Bum mom, he regrets and is disgusted. I hope Bum handles this right and consoles his fragile heart and doesn't make him feel more disgusting than he already does. Im afraid it would break the poor guy if Bum reprimands him. He needs love and understanding if Bum wants him to change or get better.
