Theory 1: Guwon is actually Sisyphus from the underworld. The disasters happening, the dead coming back to life. If you don’t know the story of Sisyphus, basically he was cursed to torture in the underworld, forced to push a giant boulder uphill for eternity. Read it, it’s pretty neat.
Theory 2: Guwon is a hound (?) from the underworld. Like a hellhound. Maybe that’s why he doesn’t understand a lot of human things? Unlikely, but I’m just brainstorming.
Theory 3: Something happened in the underworld to cause a rift in the human world, hence the disasters and undead walking. Guwon then traveled to that human world, but when he did that, he lost his memories and couldn’t remember about his life. Or something else caused him to lose his memories. OR, he is lying about losing his memories and doesn’t want to reveal his true identity for multiple reasons: afraid of losing Jinwoo’s trust? Etc.
Other: When it comes to human relationships, Guwon seems very… innocent. Pure, in a way. His appearance isn’t, but his mannerisms and personality seem quite naive and unassuming. It’s almost as if he doesn’t quite know how to take in information, or how to express his feelings. Or even knowing what some feelings are. I.E. taking off his rings for Jinwoo, showing Jinwoo the moon. I could be wrong, but I love his character so much right now.
I have a feeling, though, that Guwon is actually more evil than we think. Or at least has done some bad things, judging by how he was looking for a reason to save Jinwoo in the beginning, and he only saves people that he deems worthy since they can all offer something useful. So far, whatever/whoever is really is, I believe he’s connected to the undead and the disasters, and I believe he came to the human world from the underworld.
Other Pt. 2: I love this manhwa. Also, I wouldn’t mind if either of them topped, but I think it’s Guwon.
