Sure, we can discuss the idea of vacations for them, but that's not what this is. It's six weeks of "writers block" for all of about 15-20 pages of smut. I get that everyone needs a break and that sometimes you run up against a wall, but if you're getting writers block on the second update of a project that tells me you didn't plan out the project and you're coming up with everything on the fly (which is a VERY bad way to go about writing a story).
...second update?
you do know he made all three other books two, right? Like, this one both books have very different stories, while book 1 the main change was the relationship and book 3 was half the same half different, but book 3 diverged pretty heavily at points, meaning if you count 2 nd 3 as 1 and a half each you'd get 5 books already plus the start of book 4 love route.
also, that is not how writer's block works.
you can have everything planned to the smallest details, and yet have trouble putting them into actual writing.
you can have the chapters before and after written, with the current one completely outlined, and still have trouble actually putting the outline into readable prose.
I know because I lived it.
