Didn’t know this thread existed but since it does… I’ll link to my other post (Probably belongs here anyway)…
Did chapter 2 but didn’t do a breakdown at that detail…so didn’t share it.
In any case… started chapter 3 and ran into an interesting sentence… kind of wondering if @ChristopherFritz our resident book club promoter/detailed explanation dude… might be able to shed some light (yes I noticed you are promoting ABBC in quite a few places) haha
Anyway this isn’t manga so no frames to share, just a wall of text and the sentence is:
部室には、いつものように皆の姿があった
Not gonna bother hiding anything cuz…this isn’t a spoiler really and don’t think anyone is actively paying attention to GJBu…
That sentence breaks down to:
部室には = In the club room,
いつものように = like always,
皆の姿が = everyone’s appearance/form
あった = there was
Natural English would become:
In the clubroom, like always, everyone was there.
Since that’s essentially what’s being said…what the difference in Japanese if we say:
部室には、いつものように皆の姿があった
部室には、いつものように皆がいった (changes from ある to いる）
same English meaning essentially (or not??) Imagine this is a subtle difference in meaning that cannot be conveyed in English…thoughts people smarter than me (which is almost everyone 
)

Been doing more digging…maybe the primary sentence better conveys “there was the sight of everyone” or “there was the presence of everyone”? Guessing that’s probably a better way to read it…
Which would make “部室には、いつものように皆の姿があった”
In the club room, like always, three was the presence of everyone.
and “部室には、いつものように皆がいった”
In the club room, like always, there was everyone.
Both mean the same but the first one feels more literary and reads ‘nicer’ if I’m correct…?
