This fable is created solely for Kim Dokja.
"Ways of Survival" is made for the purpose of Kim Dokja's living. It was made to keep him Alive. Han Sooyoung write this to keep Kim Dokja safe. She even give the 4th wall to protect him. By the time KDJ read the story he give life to the characters and that is why this story is solely for Kim Dokja alone.
In this manner, characters was created and ended up living with it. The character (Yoo Junghyuk) with the curiosity of the Constellation (also his sponsor) who supported him throughout his adventure. He accepted his sponsor's (KDJ) advice of regression for 1834th times just to meet him unfortunately they did meet but YJH doesn't remember him anymore because of the effects of probability.
I have different opinion for this story tbh because I really like it but I also despise it. Just like how Kim Dokja love and hate every Fables that he read, I also love this story but I also hate it. I love the fact the this story is mind blowing, connects everything, amazing stories, and adventure. I love the characters but I also hate them. I hate it, because I was thinking if YJH wasn't curious of "who is this Constellation DKOS?" then maybe he and his companion's life during 0th turn will be the end and no more suffering. However, I also love it because during his adventure in his regression he manage to meet precious people from different world line and in the end he meet his life long comrade (KDJ).
The end is good but it makes me want to read the book again and again and again. Just like what Sookyung said "Read the book again and again and again. It will become a brand new experience each time you read the same book again".
Dang! Seems like Luca would be a good bet for shutting those yapping crickets lols
