I know you named it Custody Battles at Norsekink but I've seen that as the prompt name too (personally I find it un-special, shrugs)

Well, I saved it as "You Are The Reason I'm Here" when I first read it. It's the last sentence you used in the first fill and I thought it had a punch to it. Literally the phrase that made me think "Oh! This is good" It also makes more of an impact reading Erosion, like "kid, you're my lifeline"

Anyway, I hope I helped some even if just to show how much I liked your fic.
