what i don't understand is if iheon lived thru that og timeline and didn't want them to be doomed this time around, why was he acting the exact same as his og tl self in the beginning of this manhwa? (being cruel to huimin, almost assaulting him before huimin started yapping about his sisters, etc.)
Mc has DID. What happened was:
1. The real world, 'Silence' is where all the things happened.
2. After all the k!dnapping, r*pe, etc., when he was su!cidal, Huimin wrote and drew a scenario where Iheon was his friend, and he had another family in order to try to escape from the reality he was in.
3. They died like in the novel, HOWEVER they turned back time. Both had their memories of the alternative future, however Huimin's mind made him believe that all of what happened in the past/alt future was the novel's plot (his consciousness basically switched his story with his reality)
In a short phrase: It's actually not a transmigration trope, BUT time regression+mc with a mental disorder
I have no idea how the notebook was preserved by Iheon though
