Maybe a double suicide? At this point I don't know what the ending could be either, which is refreshing as most manga plots are quite predictable. At the end of the day both have committed crimes that would mean a custodial sentence at a prison or more likely, they would be forced to stay at a psychiatric hospital for violent offenders.
Crimes we know of so far
(Bum)
- Broke into Sang woo's house
- Murdered a woman by stabbing her at least 20 times
- Murdered that man by stabbing him
- Moved the body, hid the body
- Lied to the police
(Sang woo)
- Murdered the woman who was the CEO's daughter
- Arranged the murder of the two people Bum killed
- Kept Bum captive for a few weeks, grievous bodily harm
- Moved the bodies, hid the bodies
- Lied to the police.
(Just to say before others mention about Sang woo's parents, all that's actually been shown is that Sangwoo moved the body of his dad and buried it. We don't actually know for sure what happened to cause his death, or what happened with his mum's death)
Also Sangwoo probably killed at least his father, and likely his mom too. But you’re probably right not to add it to the list since it didn’t happen on screen and Sangwoo isn’t exactly a reliable source of information (he’s definitely a liar and probably psychotic).
I imagine them pushed to a breaking point where one will snap and kill the other
Behaviour such as lying can be a sympton of abuse, which we know Sangwoo was already a victim of. Also Sangwoo has nightmares just like Bum, why does one attract sympathy but not the other? It seems that both characters have Borderline Personality Disorder, which was the diagnosis mentioned at the start of the series, and the series is a portrayal of how this is manifested for the two men.
I doubt Sangwoo could essentially kill his replacement mother, given that they are now both so codependent on each other a double suicide because they don't want to separated from each other seems more likely (if they ever do get caught by the police).
On the other hand, Sangwoo has said he doesn’t want to become his father but resembles him in several ways. I think it could end that he indeed becomes his father and kills Bum. But like other, I really don’t know how it’ll end, or rather, I think there are at least a few ways this story can go.
I could almost see Bum killing Sangwoo in a moment where he truly believed ending his life would spare Sangwoo a great deal of suffering or if Sangwoo asked him to.
Even then, if Bum did kill Sangwoo, I believe he'd feel compelled to kill himself right after because you are right about their codependency.
So maybe a murder suicide?
Still, I can't truly sense what's going to happen next.
Although, I am guessing that the detective is going to pop back up at some point in time.
Having burned all his bridges, the detective is probably so close to losing his own mind that he's going to do something truly insane.
That'a quite feasible, especially if Sangwoo ever does manage to confess to Bum about the extent of his childhood abuse, given that Sangwo has a more "it is what it is" apathetic attitude, whereas Bum is more reactive and physically self harms. I think the detective might have been sacked after he beat up Sang woo? The detective is already a "stalker" but I don't want him to be a killer, as it seems a more fitting end if Sangwoo and Bum take their own lives, Bum "mercy" kills Sangwoo and then kills himself. I guess it's going to end in a tragedy anyway.
missed out, or. Should be "or bum"

I keep trying to imagine what a happy ending for this story would be.
Or any kind of ending really.
But I cannot even imagine what the future might hold for these two.
