I can relate to this so much! My story starts with some action, and then there are several chapters with characters just hanging out, learning more about each other, their backstories etc. And then there is more action again, but I used to be worried if my readers won't quit before reaching those chapters when action picks up.
The thing is, those calmer chapters are very important to the story and affect characters' decisions and actions later in the story. Even some very small details are important as they can be viewed differently when reader already knows what happens next. Leaving that out would do more damage than good to the story.
Also, passing time is also a big factor in 6,75, as we're secrectly counting down days to one character's birthday.
Luckily I've received some positive feedback from my readers even on those chapters, so I guess that that's okay.
Oh, and I don't think those parts are bad, they are just calmer so they might not meet readers' expectations set by first chapters.
I think that we as creators tend to overthink things like this because we already know what happens in the story, we've been seeing those scenes over and over again in our heads so they might look a bit more boring than they actually are, especially compared to other scenes that we've planned.
Well, as a reader of 'The Commune', I haven't even noticed much difference between first and current chapter
I mean, the creepy vibe is still there. And yay first mission! Why would reader find that part 'weaker'?
(unless it's not about already updates pages but further part of the chapter)
