I noticed that too, but I feel more that he has DID (dissociative identity disorder) similar to the movie ”Split” and “Criminal Minds” season 4 episode 20; I think the mc situation more accurately reflects criminal minds in the sense his split personality is “protecting” him by not only attacking others in his sleep but keeping him from remembering. I imagine it similar to when you cover a child’s eye when an intimate scene or horrific scene plays on a movie you don’t want to scar them. This is my take/guess
That’s such an interesting addition. I didn’t want to pin it on multiple personality disorder thinking I might be way off, but that seems possible. I wonder if guwon has actually met the other side of mc and actually likes both sides. Might be why he said they are similar, probably cause Guwon is a yandere type of personality.

The way that bullet flew by mc’s face, it split the panel in half and it denotes a split in personality almost like he disassociated, even his eye color slightly changes, not only that he also did not flinch, I think strong responses sort of trigger another side of him. Idk y’all, this whole thing might be an experiment being done on a specific area instead of the whole world and Guwon probably knows more than he lets on. The plot is plotting but our main character is most likely not the innocent type, I think he might be some sort of agent or something and he might have simply lost his memory, imagine if he were undercover but the trauma made him only remember the civilian part of his life or maybe he was programmed to die but broke the hypnosis? Idk, there is something similar between him and Guwon, they both have a morbid darkness about them
