So... Dokja unintentionally ate the essence of Jonghyuk by reading his story? They do say you "consume" novels! Do you just see their memories of you eat their story though? It can't be the same in Dokja's case since the novel he read had multiple viewpoints. Though multiple people have felt an odd familiarity with him - maybe he consumed all of their stories and essences and is planning to carry out their wishes now for the ending he hopes most for? So all their thousands of years of effort, suffering, and deaths aren't in vain. Like he called YJH at the start - these characters have been his companions already, even if only through the pages of a book during his own suffering.
