For it to be both true and accurate the author would have to either be N's BFF who gets told everything unfiltered, or N herself. Otherwise, thought bubbles really have no place in a true story.
...But honestly I'd prefer this not be a true story. If it's a true story then there's some stuff here that I'd find mildly concerning (starting off with slightly questionable consent in the beginning? I realize our societies tend to treat sexual harassment between women as pure playfulness, but that doesn't make it actually okay.)
