Bro this is going to be good!!
But he did come from another world right? He came from modern day korea without omegaverse and transmigrated into the book. Maybe the book life was his og life and modern day life was his second life and he just came back to his past life in the name of a book
Possibly but I think he just genuinely has D.I.D. I feel like it wouldn’t make sense for him to have a second life and then return to the fist one out of no where. Maybe if he died in the normal world but he just woke up. Like he made it up to protect his emotions. That’s why he’s just like “oh, that would be traumatic but that wasn’t me”. It also explains why everyone in his “real” world is the same as the omegaverse.
THATS WHY IHEON ASKED IF HE WOULD BELIEVE IF SOMEONE SAID THEY CAME FROM THE FUTURE. Iheon thinks he came from the future/ went back in time from death while Huimin thinks he came from another world but in reality he really does have D.I.D.
