Mc is the snake

Basically popular theory was that Kiyoon/MC was the reincarnation of Muni. But Muni is a horrible character. It seems like what happened was they used a big snake/Imugi to try to revive Muni who died(young master/pretty ghost) ordered it, so they fed the sliced up corpse of Muni to the snake which combined the two characters(ultimately trying to revive Muni.) But I think it backfired cuz Muni soul got tainted. Hence that long necked ghosts evil appearence was probably a result of that(I don't think he reincarnated as the co-worker or at all) . Kiyoon, has red eyes, is shown to see the supernatural but rejects it and is shown to hate young master (Muni was obsessed with young master). I think Kiyoon memory of the past are fused with Muni's because he consumed him.

Starts off horrendous, has an unfortunate power imbalance from the Seme. Like bruh how is r'pe a sensible punishment or revenge. Dude can read minds, can manipulate memory ect...get creative, be spooky. Seme has the nerve to call out the badmind childhood friend but thinks sexual violence and forced insemination(of whateverdafuck that creature is) is not crossing that boundary. Some idiot sold his soul for this shit, like it won't backfire in a few chapters. In my opinion the seme in already assmerized otherwise a year later and hasn't moved on? And we technically have an unreliable narrator(Uke) since we have memory gaps. What's the Seme shit head hiding.
Regardless of my annoyance with Seme weak ass motives I quite like our Mc he's shown to be quite strong so far. He's not submissive and breedable, okay apparently breedable. Honestly if the seme succeeds in breaking/corrupting the Mc. I hope the author has enough sense to make it back fire on the Seme's dumbass some degree. I once read a novel where the bottom threw the forced hybrid-babe from a cliff... Not insinuating anything at all.
Also I noticed a critique being multiple re'pists I might be wrong but I think they are the Seme's conjuration or at least apart of him since they each resemble him and have no dialogue.
Hollllld upp did Uke summon the Demon???? I can see that

This is research based off the raws so I can't go full scholar mode but any confusing points I can elaborate but not greatly cuz I need the translations too.
Kiyoon - A fragment of a reincarnation of Muni? A part of Muni that is indifferent to the young master. (I think it would be cool if he was actually the snake cuz Muni was dog trash)
Is aware of ghosts likes to pretend so much he confuses himself. Or the author shifts perspective making him an unreliable POV narrative. (The author is confusing every single fan it looks like but the art keeps us loyal)
Regardless of what ghost form the young master takes he is shown to always dislike him compared to the other two characters he is intimate with.
Manager - Is a reincarnation of young master. Often possessed by young master . Has no apparent memories of the past and I think the young master wants him as a vessel somehow. As they are basically two separate entities at the moment.
Ghost Manager/Fake manager(underdog male lead) - The masturbating ghost - The most confusing character or most mysterious hopefully on purpose not because the author is high. A demon? A ghost made by long neck? He perfers the managers form and mostly posseses him. Obeyed long neck and technically not anybodys incarnation. Likely a stray ghost.
Ghost Young master (Antagonist)- Kiyoon subconsciously treats ghost young master worse than Manager and ghost manager,which I find interesting. Utter psycho his presence is still a mystery I think. I legit don't know when he appeared probably after season 1. He ain't a good guy.
To tell the ghosts apart I think is the eyes. The fake manager has yellow eyes.
Long neck dude (Antagonist)-long neck ghost is controlling the narrative and fates as revenge? or out of obsession. A snake demon who embody Muni's obsessions. he has an obsession with reuniting Jumin and the manager, as he believes they are both incarnations of their past selves. Not entirely sure of the intention it can't be good. Or perhaps he wants to taint them. No clue. He a hot mess.
Shaman - is possibly predecessor to a older Shaman who assisted young master with his wickedness. Her purpose is uncertain but their should be clues that ghost manager points out. Later gets possessed by the long neck ghost.
Jumin- Annoying Uke co-worker - Another possible fragment reincarnated soul of Muni. Who remains obsessed with Young masters incarnated form manager. Works with long neck to monopolize Manager(subconsciously?)
Muni - Hate this guy like a pick me Stan from what I saw he assisted the young master in assaulting sexual partners(with the biggest smile mind you). He did everything he was told and the young master barely even liked him. He got sick and when dying/or dead the young master suddenly developed an interest in him. He Died obsessed with Young master. But before he did they attempted to merge him with a supernatural snake by chopping him up and feeding him to imugi who then appeared to take Muni form.
Believed by long neck to be reincarnated as someone...
___As I personally read many Asian style horror novels I suspect that it is a misdirection that long neck is the snake-spirit Muni. Although he believes he is purely Muni. I think as well as an evil corrupted spirit, this snake dude thing is a combination of victims created by young master. Or just crazy Muni who wasn't allowed to reincarnate as his obsession is too strong/ or the imugi they used could've utterly tainted his soul.___
In conclusion Kiyoon might be the Imugi. My evidence? His ability to see ghosts his attachment to that Shaman who happens to be the sister of his friend. As if they are trying to make amends with the past?? His glowing red eyes. His confused memories of Muni.
Bruhh ngl I confused myself

The author/artist are brilliant, highly underrated work! Fierce plot, fantastically rare power bottom, fuckable art, fascinating concepts, full characters, intriguing world building, subtle but extremely poignant emotions and we get a side of smut omgyad... Also it's still ongoing I could cry... Even the physical interactions during the smut is a chefs kiss. Belongs on my ad spam rather than the other so called top works I get.

So this so-called Guardian has to be a Deity or monster. Who might have hunted Seo/Min-chan in his past life. Cuz who was Seo running from? or worried about? Which explains why he 'betrayed' our Dokaebi, probably an effort to save him.
I believe Min Chan is Seo and I don't think they're human like broski where are your parents??And his granny respectfully is basically perma old... that damn guardian who seems to be able to manipulate memories, so he must've tampered with Seo's. Min Chan memories are defo inconsistent it seems like the guardian inserted himself within the memories.
My question is what's the guardians purpose? Monopolizing? Jealousy? Control? Ambition and love?
He and the Min chan seem to be opposing forces of nature so whatever there past may be I'm intrigued.
