i'm thinking the ml's original body was decapitated. someone found the head of a man named pyo guwon and stitched it to the ml's body. the ml doesn't have any of his memories because that's not his damn brain. the ml wasn't talking to himself in the mirror--he was talking to pyo guwon.
"pyo guwon you really are something else. too good-looking for your own good" = "pyo guwon your face is making teach fall in love with me"

but isn't this how many narcissists talk to themselves in the mirror? i took it as him talking to himself. so OK, the brain is someone else's named Guwon.. then everything that happened between them was experienced by guwon not by the ml? i don't get it... the ml likes teach but guwon the brain is disgusted by it?

haha it's alright. if you've seen jujutsu kaisen (geto suguru) or jojo's bizarre adventure (dio brando) you might understand it a bit more. i think the ml has full control of his body right now so every interaction with jinwoo has been the "ml". but i wouldn't be surprised if "pyo guwon" began to control the body later in the story either. for all we know maybe him puking was the man named "guwon"

never seen it neither. but i researched a bit about geto. when Kenjaku takes over Geto’s body, via brain transplant — that stitched line on his forehead, Geto’s consciousness and soul are no longer active. therefore he no longer lives. if we go by that premise, it would mean that guwon is the only one interacting with teach, no matter if it is not in his original body.

what i do understand now is that guwon might not feel real emotions. so basically he's acting. not sure how this will lead to "true" love or whatever, but it better be good. i don't want some toxic bullshit drama between them honestly. i can't take mahwas that are overly dramatic, twisted and toxic. i just can't. ruins my mood.

well rules established by other stories don't have to apply to this one. they just have similar concepts. in both examples i gave the ghosts of those whose body was stolen haunt the person who stole them. jjk spoilers but geto briefly takes back control of his body when kenjaku attempts to imprison his situationship gojo. might happen in this one, might not! only gusao knows ╮( ̄▽ ̄)╭
every single chapter that comes out continues to throw me off my shit and destroys all the theories i've made in my head.
the body is ml's. his head is someone else's--a man named pyo guwon. and he is, in fact, too handsome for his own good. welcome back dio brando.
