I like to think I'm pretty okay at getting into the heads of characters and experiencing the story from their perspective.
But if I could have one thing - it would be the cultural context that goes into calling someone by their first name, rather than their surname.
It seems like such a big deal and I just lack the relevant societal background to truly understand it, because I don't think there's a good equivalent in my country for how important it seems to be.
And I feel like if I truly got that aspect, these sorts of stories would be all the more enjoyable (and they're already fun to read, as-is).
Just...the way they both light up the room when they hear their name said by the other?
I have no reference for that, and I feel like my life is kinda lacking for it (or at least my ability to truly mesh with the story).
