I enjoy the fact he's still a jerk, in the sense that it's unrealistic for someone so narcissistic to suddenly have an epiphany that they're actually an asshole and start mending their ways. For Jaekyung to suddenly turn unto a simpering idiot whining for forgiveness would just be bad writing imho, at least at this point in time, nothing's happened yet that would cause him to have a change of heart because people like him only care about themselves.
He perceives the world as revolving around his own needs, fuck everyone else. To change that mentality would either take a pretty big shock, or an internal need to divert course because of something he feels that he needs himself. I think that's what's slowly happening with him realizing he doesn't like not having Kim Dan around for a body pillow. Even taking care of Kim Dan in the bath was more of a bother to him than a conscious thought about "hey maybe I should be considerate and wash this guy's ass out", he's never been considerate so to expect him to be kind at this point is a bit ridiculous honestly.
I get the vibes that Guwon is a red flag wrapped in green packaging. Only time will tell, but at the beginning of the manhwa didn't he crawl out of a collapsed building? What if he's a zombie? I dunno there's definitely something about him that's not quite right, the whole not knowing anything about anything stuff aside. He was also willing to just let MC expire without interfering if he wasn't 'useful'. What if MC stops being useful? What if someone else in the village stops being useful?
I also think that he's some kind of zombie; because the zombies have white iris just like Guwon's.
