i think it’s simple. mc has extreme delusions, in the last part the author showed that mc couldn’t see Jimin bc his mind dismissed his existence. He gets to subconsciously only see what he wants to see, that’s why in the chapter where the shrink asked if he can see “jihye” (which means jimin was there the whole time) meaning he still wasn’t cured that’s why the shrink insisted on him taking up his medicines. the doctor asking abt the possibility of doppelgangers, aliens n ghost was just a creative segway to not spoil the story, i think it was used to somehow make a hint on what is actually happening in the story and at the same time confuse the readers to keep them hooked. bc when i found that jimin was actually watching over him, everything kinda made sense

I thought the story would be worse bt it's okay bt a little confusing................ Like that time when the doctor was examining the ml and then when the ml says he couldn't see anymore and went out then suddenly the girl appear??? And like the story abt the blonde....maybe I'm jst dumb bt i don't really understand that part ╮( ̄▽ ̄)╭╭bt still the story ain't that bad imo
