Author: “People who argue about labels are missing the point."
What point? That the author has somehow crafted such a unique story that the entire human race has not been able to come up with the words to describe it? Doubt it.
'Deep bond' and 'love' aren't labels. They are adjectives.
Adjectives are descriptions for nouns, they are literally labels by your own personal definition. The issue is that their relationship can be put into neat cookie cutter catagories, saying that we simply can't is just ridiculous. Everything has a label and if the author somehow comes up with a situation that doesn't then we will make one. 'Girlship' seems to be the hot contender here.
