He should suffer more after all of the things he did. I mean "hey you raped me but we like each others so it's not a problem. Ok. " shouldn't be an option.

If you read through the "make up" scene again, Hyeonjo never made excuses for what he did, he just apologized and admitted he did wrong. It was Minjae who chose to forgive him, Minjae was hurt by the rape, but decided that he loved Hyeonjo and that that feeling matters more than his hurt feelings. If he chose not to forgive he'd be giving up a life with the one he loves who, might i add, just got on his hands and knees apologizing for everything that happened. Personally, i would've done the same in his position because Hyeonjo is clearly showing remorse and is horrified at what he did. I don't feel like he'll repeat the same mistake. Obviously apologizing doesn't make what happened okay, but it DOES show that Hyeonjo recognizes that he needs to treat Minjae better and shows that he's willing to improve.

Now i'm thinking that words in the title, killing and stalking, both of them were for Bum, huh?... I mean the real psycho in here is not sangwoo anymore. My brain just f.ed up

they are both wrong in the head, traumatized and crazy

Well the main character from the start IS Bum. And now that I think about it, it's from his POV from the start, so holy shit maybe KS IS Bum. (╯°Д °)╯╧╧

Just because he has BPD doesn't make him a killer. Ordinary people with BPD don't fucking go on a murder spree. I suggest you educate yourself first about this before spreading your opinion about this.

I am not an expert about this so sorry about that.... You seem to know more about this, please tell me instead...
If i just use internet, maybe it will just confuse me more cause i did try to look up and it was hell comfusing... BPD is s complex disorder and it takes hours to weeks for the disorder to occur, that is what i just remember from it....

No one knows everything. It's just that mental illness is sometimes misunderstood. That makes some people defensive. But it's not as if everyone has studied every subject. As you said, BDP is complex. It is not something that takes hours or weeks-- it's more like a chronic illness someone lives with all the time (like being diabetic). But you just want to look at this one fictional character, right?
So in this story, we need to look at how the "world rules" set up by the author treats these particular people and their mental illnesses in context of this story. Would you say is fair to see Bum's condition as having escalated and developed differently since he has been with Sangwoo? I mean, the killing was new to him and it seemed to be a significant turning point for this character, right?

The point of my counter argument to her was that people (like her for example) already associate BPD with murder. And I think that's unfair to the people who actually have it, it's unfair to what BPD is itself. I don't think she was thinking of the things you pointed out prior to that. If you look at her response, it implies seems to imply that she's accepted already that BPD makes you automatically a killer or a stalker, even for Bum, a fictional character, that's quite unfair. Like you said(and I agree) , the mental shift of Bum's "quite normal" (he was a stalker but his mental state was still bordering normal lol) mind before to the "cray cray" version is hugely influenced by Sangwoo and what Sangwoo did to him.

Well, my point was your analysis of WHAT you think BPD is quite false. Don't go riding on other people's coat tails. And your misinterpretation has a direct effect on reality, whether you like it or not, whether you intend to or not. Fiction would always have some kind of influence on reality and vice versa. So, yea, I stand my ground. Go research first before you go spreading information

I agree with you about the character changing after Sangwoo, but I think it helpful to make some allowances for people not knowing everything about BPD or any mental illness. I know why it makes you mad when people have false ideas about it in real life--but no human is born knowing everything, and people can't be expected to understand things they have never had a chance to learn.
But if I keep explaining, people will (rightly) tell me I'm off topic and I should stick to talking about Killing Stalking. So I'm going to try to be good. That's why I think we should try to focus on this story and these characters.
I do think Bum's personality disorder was a factor in both how he got to be with Sangwoo and why he was so vulnerable to Sangwoo's manipulations. Bum was clearly not taking care of himself or developing effective ways of dealing with his issues before this. Sangwoo got Bum to the point where Bum let all the rage he was suppressing and turning inward at himself was released as he killed. In a twisted way, this like a coping mechanism some therapists may teach (only they would want Bum to create art, music, or whatever Bun could get into instead of killing).

I never implied or said that they should know everything about the illness. However, it would be better that they should AT LEAST attempt to be a bit more informed about it, before spreading their opinions about it. It's quite hard to not sway away from reality when talking about the characters. Especially regarding Bum and Sangwoo. We analyse them (whether for future chapter predictions or for just a plain character analysis) of course within the limits of the KS universe, but we inevitably would also tend to rationalize their actions based on what would ideally happen in reality. It's okay to integrate reality with fiction, especially for predictions/character analysis/fan theories. (Especially since BPD is an actual real life illness which the author had used in the series)
Tell me if I'm not making any sense, I'm currently in public and am typing on my phone so ┑( ̄Д  ̄)┍
Oh, yes, I agree! I'm glad you brought up the coping mechanism thing. I think the same, however, I relay that to Sangwoo. Killing may have become Sangwoo's sort of coping mechanism. Like, it's a coping mechanism he accidentally discovered during his first kill. I saw something in tumblr about how Chapter 19 is Sangwoo's way of sharing this type of coping mechanism with Bum, thus forming a deeper bond with him. And I totally agree with it, I also think that the killing of Jieun has been used as a stepping stone for their progress in their relationship. And the author seems to also be implying exactly that based on the things she's been posting recently lol.

" I also think that the killing of Jieun has been used as a stepping stone for their progress in their relationship. "
Oh yes. This is an intimacy that is more than sex (for Sangwoo). When he engineered the "gay slay", Sangwoo made apoint of telling Bum "You used to be like that." and Sangwoo spoke of arranging the Jieun killing for Bum as a way they could be together. Now Sangwoo can trust Bum won't run, because after killing like that, Bum is in it completely.

It actually quite saddens me to see that there are people who hate Sangwoo for superficial reasons. While I understand why they feel that way, it seems to me that their judgement about him is abrupt. Idk in my opinion, Sangwoo's character is quite complex. There has to be some character dissection to have that kind of grasp of him. Like, I actually think some of the hate he gets comes from conformity of the opinions of others. I remember I used to be afraid to share my liking for Sangwoo's character because it seemed like a taboo thing.
Like, I also think that what Sangwoo feels for Bum isn't superficial. We can't exactly define what that feeling is, but I'd wager that Bum has a "special" place to Sangwoo. I've seen people say that it's purely manipulation, but I disagree. I think there is genuinely something in there, albeit it be in a very fucked up way. I'm actually quite excited of what that "bonding moment" in ch19 would entail for both their characters and their relationship

Ok guys i'm seeing this alpha beta and omega thing lastly in a few manga but i don't know what it is. Is it a new term? Can someone please explain me this with simple englis bc as you can see my english is not very good.

Omega = guy who can give birth
Beta = regular guy/human
Alpha = guy with make omega pregnant
Alpha + Omega = babies
Omega has heat cycle = menstrual cycle
(●'◡'●)ノ

Yes, i was very confused at first too. So this is kinda a new trend, someone wrote a doujinshi, and the idea spread like wild fire.
Basically the world is divided into Alpha beta and omega. The beta are the normal guys. The omega gets in heat and can get pregnant. The alpha is the high of the hierarchy and if sexually attracted to the omega.
Then depending on the story it can change a bit:
In some mangas the alpha is so attracted he can not bear it and normally it ends in rape when the omega gets into heat
In some mangas there is something as the fated pair between an alpha and a beta. Normally its like "love at first sight"
For them to be paired the alpha has to bite the omega's neck.

Here is a nicer description xD
But that's about it.
Again, that grin may be really cute and pure but it looks like ( ° ʖ °) to me
