Might as well throw my hat into the ring now that I’m far enough in where I think inertia will carry me.
Day 5: 
Read some more Ryuugajou Nanana no Maizokuin (40 → 43%).
I basically haven’t actually read Japanese in a year but I’m surprised at how much my skills haven’t deteriorated. Aside from grammar (but the grammar isn’t very hard in this).
Um interesting things I guess. There’s a book by K. M. Weiland - Structuring Your Novel - where she puts forth the idea that the majority of western novels have plot points at 12.5%, 25%, 37.5%, etc.
In contrast I’ve noticed that (in my experience) Japanese novels tend to use this kind of three part plot system (or smth, as opposed to ~8). Lo and behold, the foil to the thief protagonist, a detective, shows up at exactly 33% into the book.
Might just be my upbringing but I do feel like the western pacing is superior. 33% is wayyy too far into a book to finally have things start happening.
