@intmanga they've been around each other practically since they were born because their moms were close, I think childhood friend is a good way to put it
@Doodads What I mean is that they are in elementary school, they are literal children so that means that every single friend that they have at that point of their lives is a childhood friend by definition.
@intmanga sure, once you'll be older. But from her perspective as a kid, "childhood" refers to the past, not the present, which makes perfect sense. You don't define your current relationship with others according to what they're gonna be years in the future.
