Good thing but....

It seems that you had really much in heart. Even if I agree with you, I will try to answer to your questions point by point.

I'm also dissatisfied by how the events of the kidnapping were unfolded, it was one of the weakest arc (if we can consider it as one) of the entire manhwa. It was really anti-climatic for all the building up that was behind.

Considering Lord Min as an NPC, doesn't do really justice to the character. It is certainly one of the minor characters but think another way. Who was the one suggesting to Jihwa to kill Nakyum ? Who was the one making Seungho realise that he was falling in love with Nakyum? He said it himself that he can always count on Jihwa to make him entertained when it comes to Seungho. He is the mastermind when it comes to all that happened leading to the kidnapping. Read chapter 36 and chapter 47 back to back to understand what I'm talking about.

Seungho was presented to the readers as someone cunning, who is a move ahead of some people, but when it comes to Nakyum, all those characteristics go out of the window. There were many hints regarding Nakyum running away, but he was too blinded by anger to see the ones providing his innocence. If he has searched thoroughly, he would have found. He didn't want to listen to his servant trying to persuade him. Min being a noble, Seungho is more eager to listen to anyone with a status closer to his. He also noticed Nakyum's bruises on his right hand when he raped him, bit didn't give it any thoughts. When he learned the truth, he is gone for the same hand and placed it in his forehead, he already knew something was off and he just confronted his own stupidy.

About the trauma, it is possible as @Pacgirl said, I will even add that it wasn't the two hours only that lead to his trauma. He was also locked up by Seungho for a day, raped all night and he lived the same scene as the kidnapping with the hands tied and the obscurity, before that Seungho threatened him twice. It will be too much for anyone to take.

For the sister, you can dislike her if you want, fine. We can only speculate when it comes to Nakyum with his kisaeng sisters. We know that he was happy with them, but he was also growing older for him to stay there. Maybe there is a event we don't know of that lead to his departure, but I'm sure of it that his sisters liked him very much. A little correction though, they didn't tell him to run away. They told him to go with In-hun as he liked him and wished for his well being. They advised him not to come to the kisaeng house anymore. She even added a little information that Nakyum despise nobles and would have never come there on his own volition, which is true.

I don't really think that Seungho will want to let Nakyum go even after those events. It will be a good subversion of expectation, but knowing the author I highly doubt that.

Thank god someone gets what I'm trying to say.... thank youuuuu

Yeah I never thought the story was amazing, I am literally the person who reads it for the sex scenes and nonsensical drama. I won’t go on my full on rant about this story that I’ve had since chapter one. But I don’t think this story is anything great in terms of presenting mental issues in its writing. I do think Nakyum reaction to getting traumatized by the kidnapping is realistic. Along with his “acceptance” of how he gets treated by Seungho. Which could be seen as textbook Stockholm syndrome. BUT if that was the intention, I don’t think the author shows it all too well. For example in the story warehouse there was a period where the MC just broke down and went full on stockholm/mind break, but before that it showed his panic and struggle, and the initial trauma he experienced. Not that Nakyum never panicked, but there wasn’t much escalation. Like his mental state skipped a step. Now before anyone gets on my case for this. I’m not saying mental issues in real life require steps, the human mind can be rational, irrational, and unpredictable, but I’m speaking writing wise. Though I expected Nakyum to breakdown at some point. There’s not much in between to give the reader a hint that Nakyums mental state is deteriorating, which is why his trauma feels quick to readers. Of course I do think another way the author could’ve dealt with it was what shizu recommended which would be extending the length nakyum was kidnapped for, and adding some physical abuse.

!!!!

36 and 43 for the chapters with Min and Jihwa.

That is what I mean! WOW! Haha...I feel so grateful that someone gets it, too. This makes no sense at all. None. His ptsd sure is understandable, but that he ONLY has a reaction to the 2 h kidnapping and not the "being raped into a coma" is kinda.....especially all the mental and emotional abuse he went through always fearing to fucking DIE because he doesn't do what seungho wants and not just serve him normally but have to watch him fuck others and than having to accept him fucking you later whenever, however and how long he wants...and what people seem to never want to understand is....that RAPE CAN FEEL GOOD....yes....and that is why so many rape victims have such insane mental issues.....cause they felt good from being raped....rape is rape....even if it feels good....the feeling good is just your body reacting to a stimulus if you want to or not and to some extend is also survival instinct....if your body can, why should it not feel good and rather only feel pain? it is very complex, but yes. and people don't wanna see that....and the author is showing a bit in nakyum, in how he got quieter and meeker and like seemed to be "empty"....which is a weak form of a normal symptom of trauma after what he went through....i pray he will show it all properly if he finally is not tense anymore cause he is in life and death circumstance 24/7 and can properly let it all sink in and show a reaction....i want seungho to suffer from seeing how he broke nakyum and realise he nearly killed this kid....i feel seungho went through some kinda sexual trauma hismelf....so if yes, i would almost be happy like a real sadist myself if he suffers even more cause he finally for fucks sake thinks with that rusty brain and realises he did the same if not worse to a vulnerable person whom he also even loves....irony bitch....i want nakyum to be able to go live a nice life please....i want him to learn from this as well and be strong and independent and confident and one day may be find a proper lover for life or what .... and seungho be the bitch who slowly withers away realising that he could have had that, but he was so lost in his twisted way of seeing the world and HUMANS he broke it from the get go...

especially when your life depends on your rapist....this is what you call STOCKOLM SYNDROM.....starting to feel postiively about your rapist cause of survival instincts...so you won't always have to feel the torment of the actual rape, but lie to yoursel fit is consensual, cause else your brain will self destruct...

I know he is a "provocative" character and was the one that hinted jihwa to do something to do with the painter...but it STILL doesn't make sense that seungho would believe HIM pf all people in the mindset he was. Him being surprised by Nakyum's WAY too delayed PTSD reaction - tbh it looked to me like he was realizing that he did to him what was done to him in a fit of anger and he was regretting that, NOT realizing that he was kidnapped. Lmao that would make even less sense than this bullshit.
I'm calling this lord an NPC because despite his intentions, he's not someone who would sway Seungho's mind when he's THIS crazy mad. Lmaoo...if he did this way later in the story when seungho had fully taken out his anger on nakyum's annoying sister, and nakyum as well, I'd take it. It was too rushed...
This whole kidnapping arc was built up and then squashed so illogically...this was supposed to be Seungho's redemption arc NOT JIHWA'S hahahaha

I get people who wanna take nakyum"s side because he's the eternal victim...but I can't take it seriously when the build up was so huge but the kidnapping was just for 2 hours and that too with no injuries whatsoever. You're telling me he got scared shitless by some threats by a stranger when seungho had threatened him much much more for most of the story????? Sorry it is too ridiculous.

I get the situation at the kisaeng but why tf is she acting like a vigilant justice hero when her telling him he should never return is literally why he couldn't run away when he was at his lowest point...also, it seemed like in hun had abandoned nakyum for A LONGGGG time before seungho found him. Sorry but her offended and 'I'm here for you" seems so cringe.... I'm lowkey upset to see her introduced here so randomly????? Idk

I must say your comment works as a great recap of some plot points for me.
And as someone who doesn’t get what the author wants to do with Seungho at this point. You summed up pretty much why I’m kinda bored of his character now. Before I was interested in his character as he was the typical high tempered person you usually hate in these rapey stories, but he also had a brain on him which made him feel a bit more original. This brainless version of him we’ve been seeing in these recent chapters only disappoints me. I don’t expect him to be Light from death note levels of strategic and observant. But I expected this arc to play out with him coming to the answers himself, without needing a blunt, Dora the Explora like, hint from green dude.

Isn't just so convenient NK's got minimal or no trauma after SH's mistreatment?
And that later SH tied him in very similar way to assassin's bondages and it caused the attack?

Exactly...

Min is a cheap Deus ex machina at this point if I can say it like that. It would have been better if Nakyum spilled the beans to double down the fiasco that was the kidnapping, but the author, with her fondness for smutty scenes is gone down the road of rape for Seungho's anger management. Everything doesn't really make a sense but like I said Seungho can easily lend his ear to anyone of his status. As for what he was realising that he was reversing roles for NK, that could be the case. I was talking about the afterimages Nakyum had after Min and Seungho's convo.

Concerning Nakyum, I don't really like the eternal cute victim characteristic. For someone who came as struggling his own way when antagonizing Seungho to behave now like classic cliché uke is a downer. His trauma caused by Seungho was shoved in his ass when he gave into sex after In-hun called him a prostitute, so that's also a weak plot point from the author.

I won't complaint about her introduction since that's the way the author wanted her to get in the plot. Like I said we don't know the events leading to him not having the privilege to stay with his sisters. Maybe, they thought it was good for him to stay with In-hun and I doubt that the learned sir in name would have kept in touch with the kisaeng. Even if we know as the readers that In-hun probably abandoned Nakyum, it wasn't the same for Nakyum. Why would he still love the one who abandoned him? He loved him before and it's not the case now. I won't hate her for now since her offense is valid given what she knows. Where does she say "I'm here for you"?

You had me at Dora the explorer! But I totally get you!

YESSSS I totally agree...
Tbh I really like his character because it HAS some character to it lol. Even Jihwa is a more interesting character than literally the main character (i.e. nakyum)
You have nooOOOOO idea how long I've waited for someone to say that Nakyum's going down the "I'm a whore because in hun said so" road. Nobody wants to believe it, but he's the one who gave seungho the green light, that he really wanted to be fucked by him (he said that in his own words a lot of times) their sex has been consensual for an odd 20 chapters now at least. Even if he was doing it to become his "whory self" - I was sooooo put off and annoyed by that development in his character, because he knew exactly what he was doing but everyone insisted he was still a "poor helpless victim" - no I think he grasped the situation and adapted (unfortunately he had no choice) but now again...he goes back to being one-dimensional....
At least in warehouse, the traumatic shit the uke went through (which was much much worse) and he CHANGED himself.... not going "round and "round in the same circle of crying and weeping every chance.

HE SHOULD have told seungho! Even if it was scary...didn't he know seungho liked him?? Lol. I understand why he was freaked out, but bruh... it's been 60+ chapters, you've seen a lot of shit, this shouldn't be a shock anymore aish! I'm really disappointed that seungho didn't save him from the kidnapping and dealt with the nameless man and jihwa reveal should've happened like that....ugh....oh well, let's see.

This was so weak...I can't Min casually insinuates Jihwa and seungho is "oh shit you're right. I messed up! Thanks buddy??" What...is happening....

I'm reserving judgement on his sis, but rn I'm not thrilled about her random appearance. Especially how she entered the story...there's something annoying about someone who comes through long after you needed them. She should have told him "you can go with your teacher but if you have nowhere else to go, you can always come here" - like she totally abandoned him?!?!? We're not even sure if she's his real sister so whatever. Maybe I'm just pissed off about the story overall to appreciate any new "heroic" characters appearing out of the blue to deteriorate the plot into an even more cliché mess.
