Chap 0 is the prologue. The original story where Choi Han is the protag and the title of the book is "The Birth of the Hero". (Pls refer to the synopsis)
Chapter 1 onwards is Cale Henituse's POV. Cale Henituse's soul is a transmigrated soul from Korea. Cale (or the one who is in Cale's body~ if I said any more it will be too much spoiler) has read the novel up to Vol. 5 of "The birth of the Hero" where he is a minor villain.
Hope this help
If u hav other questions just ask~
I dont understand the chapter 1 and 2, more specificly who is cale? Chapter 1 seems to be a reader's point of view in the novel, then in chapter 2 that person became cale? So thats why he knows all the details? Because we already read it?
