I knew Bum was going to kill someone at sometime but I didn't know he was ready DOING it. Now Sangwoo is looking his shut and soon or later Bum is going to kill him too.
Why would Bum kill Sang-woo? I think it's more likely that Bum would kill someone he thought was taking Sang-woo away from him, or he would harm himself if he thought there was a possibility that he would no longer be with his "favourite person" anymore. Bum is probably getting agitated a distressed waiting in the ski lodge for Sang-woo, he is probably getting worked up thinking he is being rejected. I haven't seen the next chapter yet, but if we are making speculations about murder, Bum might lose his patience and go looking for his man, and sees Sang-woo panicking, he then sees the cause of it, the injured woman & child and gets frustrated that not only have they reduced Sang-woo to such a state, but they have been the reason why Sang-woo was away from him for so long, making him angry then he is the one to end their lives. ?? I'm guessing/hoping that we get some insight into Sang-woo's mother's death, seeing as it is playing such a huge part in his current behaviour. From the comments it seems like we do, although I'm not sure if this is from only Sang-woo's perspective, or the actual perspective. I think it's believable that his mum was very unwell and then went to try and kill her son, maybe she thought he was his dad, as Sang-woo has delusions about his mum screaming at him saying he is like his father. Sang-woo then ended up, in self-defense killing her, and he appears very tormented by this.
What's interesting for the future plot development, is that Sang-woo himself has only been known to kill two people, his mum, and he says he killed the CEO's daughter. These are the murders which still haunt him, the scene at the BBQ place where Sang-woo started to blurt out the details of the second murder maybe gives more insight into his motivations now. He says that you can kill a woman, but she keeps coming back. Maybe this is in reference to how he constantly hears and sees his mum, or that he thought the CEO's daughter was his mum when he killed her, just like how he saw his mum in Bum and also the woman on the ski slope....
Now without going in the first part of ur comment, from what we know is that Sangwoo killed his parents, the CEO Daughter, some woman in Chap 5( http://www.mangago.zone/read-manga/killing_stalking/mf/c005/41/, the older man and intentionally made Bum kill Jieun.
We don't know if Sangwoo killed the lady in the newest chap though.
Either way, he's fucked if she survived it or Security cameras recorded him.
What's odd is that the woman & child could break through the barrier, and presumably lie in the snow for this length of time without it being flagged by the security cameras or noticed by the staff. Yet Sangwoo by coincidence was the one to discover them. It surely would have raised eyebrows in the first place to see a child out on the slopes so late at night, so the whole set up seems rather suspicious. I'm guessing Sangwoo goes into a psychosis and will recreate whatever behaviour he had in regards to his mum's actual death. He was likely scared and probably ended up strangling or stabbing his mum after she tried to kill him. The speculation post was more on how Bum is behaving in the mean time. He probably is getting agitated over being left alone by Sang-woo and it's his response to seeing Sang-woo in such a state of distress that will be interesting. I'm guessing Bum feels like he could murder the person who not only took Sang-woo away from him, for the hour or so he left him to ski, but made Sang-woo, who is his obsession, who he relies on, who he needs due to his bpd, to be reduced to a wreck. This is just speculation though, others who have read the chapter might be able to confirm what does and doesn't happen.
Also true. Spoilers beloooooow...
I was actually a bit surprised that Bum didn't try to comfort Sangwoo when he noticed Sangwoo was sobbing. Maybe Bum was still on the brink of a deep sleep or maybe he was afraid to try and comfort him not knowing if he'd get another vampiric bite on the neck or an ass beating. Bum is intelligently cautious.
Now I can call that b!tch a Jalapeño
