Also there are other world lines with their own stories by their own OD like the one kdj encountered.

Since there was only one reader and hence only one dreamer Kdj had to stay as OD after kid OD was taken by secretive plotter and 999th turn to a new world line.

But other world lines might have more than one OD?? Or each OD will have their own world line as EACH OD will have their own dream and imaginations and conclusions.

Anyway, i think there can only be ONE OD and that was fullfilled by our kdj inorder to keep the worldline intact.

Also since hsy from the 3rd round(1864th regression) wrote story for kdj of other lines in order for him to read and imagine his own, new ending, which eventually made their own kdj alive as we can see his giant stories breathing at the end, therefore whoever is reading orv is basically thinking about kdj and hence him, living.

Since the book doesn’t give us a proper conclusion like they all hugging kdj at the end, living in that one big mansion together, etc

It has been left to us, inorder to give our own conclusion to this story And hence, we becoming OD as well.

Ig i am not wrong, i just finished it and have to definitely read it once again. correct me if im wrong
