It’s not. I wrote chapters 1-19 in two weeks. I’m just doing uni with a lot of placements to get in any editing of chapters done. It's kinda fun re-reading them and seeing what my sleep-deprived brain wrote, and those “3 days off” chapters were written with a very sleepy brain just filler chapters, really, only little bits of them get mentioned in future chapters. Still, I wanted to change cannon somehow to introduce 1a to the big 3 quicker, and that's how it turned out.
