this is so good
i feel confused what is real in the story because of yuwon narration

my theory
Looking at it this way, it seems that Yoo-won has schizophrenia. Do-hoon knows it and takes care of him, but Yoo-won seems to think that everyone is delusional and harms him.. The original symptom of schizophrenia is a delusion that everyone around you will kill you?? I heard it's similar.
