Regarding Guwon's identity and actions, a thorough re-examination of the narrative reveals several key observations.
(1) Guwon's emergence from the rubble (Chapter 1).
(2) Guwon's ocular characteristics (Chapter 3).
(3) Guwon's statement concerning sleep (Chapter 15).
The hypothesis that Guwon is a member of the undead population is supported by his initial appearance in Chapter 1. His survival, seemingly unscathed, amidst the collapsed structures, coupled with his detached demeanor amidst the surrounding chaos, warrants further investigation.
A previously overlooked detail is the similarity between Guwon's eyes and those of the undead, specifically noted in Chapter 3 during the altercation. The visual congruity between Guwon and the deceased individuals strengthens the aforementioned hypothesis.
Finally, Guwon's declaration regarding his lack of sleep, and the subsequent first instance of sleep in Chapter 15. What is the rationale behind the mention of sleep?
Three potential explanations for Guwon's identity reveal emerged from my analysis:
(A) He is an atypical variant.
(B) He is the virus's original host, possessing inherent self-awareness.
(C) He is an experimental subject, inadvertently released and subsequently exhibiting unforeseen consequences.

Yesss, exactly my theory! I feel like a lot of people in the comments are bashing Guwon for his actions in the latest chapter on the assumption that he is a normal person. Yeah, I don't think so XD he is literally so suspicious, just look at his appearance alone T-T and then all the "subtle" clues that reinforce this feeling that someting isn't exactly right...

Acknowledged. Interpretations of Guwon's actions diverge, ranging from pragmatic environmental adaptation to assessments questioning his rationality and ethical conduct. The affirmation of his humanity remains highly contentious.
Guwon's identity is paramount when analyzing his recent behavior. His apparent development of emotions and behaviors suggests an assimilation process within the human population. (づ ̄ ³ ̄)づ

That is my theory also. Not to mention that in chapter 8 when Jinwoo remembers hugging Guwon in the storage room, he says that Guwon was ice cold. I'm not sure if it's just in his memory or if Guwon really has a body temperature that is much lower than anybody else. Curious what else we are going to find out.

I concur. Guwon's body temperature presents further evidence suggesting a potential state of undeath. While individual body temperatures can vary due to environmental factors, underlying health conditions, or inherent physiological differences, the narrative's avoidance of a straightforward description of coolness, instead alluding to a deviation from the norm, is noteworthy. The accumulating details strengthen this hypothesis.

I don't know why I feel MC is going to lock his partner up. He gives off a possessiveness that borders on psychopathy and insanity. One reason might stem from how his family deals with things, and the other from missing a huge chunk of his sanity that caused his restlessness when he lost not only his memories but also the love of his life. Either way, his family has gone about this all wrong. ╮( ̄▽ ̄)╭

Not in the least?
Out of all the possessive semes I've read about Yoonsung is by far the least psychotic or possessive lol
He's worried about Ha-kyung being hurt or suddenly vanishing like he did last time, sure, but that all stems from his trauma coupled with the failed suicide attempt and near death experience. It's not like he's an obsessive stalker lol

Excessive possessiveness does not necessitate obsessive behavior. Consider his actions in locating Ha-Kyung during their separation on that rainy night. While the label of "stalker" may be contested, the intensity of certain actions is undeniable. His trauma-induced fear of loss is acknowledged; however, it's equally important to recognize potential psychological instability.
We can only await further narrative developments.

You said it "borders psychopathy and insanity" but you don't just become a psychopath. It's usually something you are born with or comes with some sort of physical or mental trauma which also comes with an almost complete personality change.
Him stressing about Ha-kyung's safety, which is warranted given his family and how far they'd go to remove Ha-kyung from his life permanently, is perfectly normal for someone who is so deeply in love. I'll admit that he does need help with dealing with his trauma, but he's nowhere near just locking someone up. He isn't restricting who Ha-kyung can speak to nor is he barring him from leaving the house. It's not like he's got separation anxiety either given that he's still actively going to work and doesn't meltdown if Ha-kyung leaves his line of sight.
I think you're reading too much into this tbh. I can see him asking Ha-kyung to contact him frequently if he leaves the house till his family finally backs off, but he's confident now that Ha-kyung won't just leave him so there's no reason for him to be possessive or overbearing to the point of abusive behavior.

Oh, come on, you forget so easily! "We'll just have to see what happens next," huh? The characters are practically screaming red flags, how can you miss it? If you wanna excuse his behavior as just stress and trauma, go ahead. But am I overthinking a good or bad story, especially after a supposed romance turns psycho? That's totally normal, right? But should I just shut up because I disagree with the popular opinion? Nope. I'm not ignoring those hints and clues that might change everything. We all get to say what we think until the end, that's what's great about this.
Therefore, discrepancies in perspective are expected. While we acknowledge the protagonist's psychological trauma, we must also consider the impact of behavioral and environmental factors. His familial background, socioeconomic status, and social standing are undeniably significant. However, how will these factors evolve throughout the narrative? Will they remain static or undergo transformation? Furthermore, are supplementary narratives planned following the resolution of the central romantic conflict? Finally, are the currently assigned genre tags truly comprehensive for this story?
Have you considered how frequently misleading genre tags, particularly the omission of "psychological" in stories labeled "romantic," appear in yaoi? Therefore, I will remain cautious until the story concludes. I am becoming quite enthusiastic. ლ(´ڡ`ლ)

Sharing parts of a novel with someone who hasn't read it is inconsiderate, as it diminishes their enjoyment. I understand your interest in discussing flag colors or story depictions, but doing so after spoiling the story is unfair to both readers and authors. While freedom of speech is important, revealing spoilers without warning is disrespectful. Perhaps you meant to make a point, but why share the novel's contents in this way, spoiling it for others?
Certainly, highlighting plot differences that began as a joke now gives me pause. When did my post prompt such an extreme reaction? It was never my intention for things to escalate so drastically, revealing novel contents. (╯°Д °)╯╧╧

Dude, this manga is so messed up, it even triggered my own trauma! I usually have a high tolerance for stuff, but this? This made me furious, especially that fake kidnapping and assault. Why would anyone do that to someone? I couldn't shake the thoughts; how is that kid okay after all that? Nightmares, anyone? I get it's yaoi, but a more realistic recovery would've been better. Like, maybe him lashing out, shaving their heads, or giving them some permanent perineum tattoos. Seriously, if you've been through something like that – robbery, assault, whatever – you don't just get over it in a panel or chapter. Okay, rant over.
Is there a concern that the child may be a vector for the virus? Let's review the virus transmission modes.
(1) Is transmission via a deceased individual possible?
Is proximity transmission also a factor? Given a potential illness, is his immune system compromised? What were the father and son's arrival times in the town?
I do not believe the boy has a cold.
Ohh that would make so much sense. Since the civilians are aware of what will happen should they do something against the "rules" it just wouldn't make sense for the guy to be that desperate for medicine for a cold. That is unless the cold was just genuinely THAT bad, but idk!
Moreover, if the town physician lacked awareness, why was the father murdered to obtain medicine? The child's symptoms remain unaddressed. Finally, what is the medicine's exact formulation?
