I hope the pace picks up again soon. I can see the author enjoying to take their time uncovering what they built up towards (except there never was a whole lot of buildup, most of it just seems like recently made up asspulls to me; see Usogui or more famously Ansatsu Kyoushitsu for a master class in how to subtly spread clues for later twists) and I probably should care about these revelations but I really don't, at least not the way they are presented here.
Come on author, blow my mind. You managed to do so in the past, why would you come and present the big framework that lead to everything in the most boring way possible?
