Finally someone pointing put the vomiting & kissing may not be related at all, i rlly think author is trying their best to make everything seem like a misunderstanding to reveal the plot twist and people are falling for it too easily
I've definitely talked with more ppl who think so too, it'd be too superficial of a development if it was just him being disgusted by the kiss. He literally seems to have a different personality in the bathroom scene. Even if he was lying abt having amnesia (though I'm more inclined to believe he legit has 2 personalities) and all that, he is STILL blushing so hard, so it's def NOT disgust that he's feeling.
Exaaactly. Also abt your other theories, for me I think he may be a geto/kenjaku situation, like pyo guwon is the vessel and sisyphus the personality we see. Bc his amnesia is weird, people with amnesia usually forget abt who they're but they don't forget ordinary things, even if he used to be a maggot he could still understand humans. But guwon doesn't, his understanding of stuff is so off it doesn't seem like he ever experienced humanity but if his a entity that ended in this body to fulfill the cursed he already loved through once? Idk it sounds cool
When I say he has amnesia, to me that's what happens when they turn into a zombie, losing any memories and knowledge from before. So that body, combined with the transferring of a living person's consciousness ends up in this dual personality state. I think it's an experimental procedure and he was one of the first to undergo it. Which is also why he's been charged with the responsibility of the town, which is somehow connected to said procedure so they can perfect it and like avoid the dual aspect, so only the living consciousness remains in the body.
But I really like your guess and it'd be so interesting to see what kind of entity that would be and what would it mean re: recurring world apocalypse.
Teacher never thought he'd be giving a lesson on THAT subject, but he's not complaining.
Also, my early guesses about Guwon are
1) The throwing up has nothing to do with him being insincere with their intimacy, but it's a physical reaction bc of smth else going on with his body/mind. Blushing like that afterwards means he either lied about everything but still finds teach cute or that he said the truth and the other personality is also affected by the kiss, but in a more expressive/experienced (human, even) way.
2) I alr guessed that he had amnesia and (again, unless he lied abt it all) now I think part of it is having another personality that does remember the past, but no idea how&why the other is activated except that it happens at night instead of sleeping. The fact he slept through the night seemingly for the first time in this ep. maybe shows he let his guard down and the other personality didn't take over, but could it have repercussions for the town if he's not there to watch over at night with the memories/knowledge of the other personality?
3) I think he's a zombie that was experimented on and fused with a living person's consciousness so they could achieve immortality, hence the 2 personalities. But what's the purpose of the town then? To gather capable living humans so they can also be made immortal?
So many scenarios and Jinwoo is even more of an unknown, but I think he mostly had to make tough choices for his survival. Anyway, I'm just speculating and theorizing cause it's fun and the author is making one of the most interesting stories, I love them for that!
