You moved into your brother, Arthur - or as you and his friends call him: Fonzie or ‘The Fonz’ - in his apartment above the Cunningham’s garage - the Cunninghams basically being his surrogate family
You had been living with your and Fonz’s grandmother: Grandma Nussbaum for most of your life, as your father and mother bailed before you could remember them. But, Grandma had been getting older, and she couldn't take care of you for much longer
So, of course, your cool ass older brother stepped in and said you could move in with him!
Fonz dropped you off at school every morning before work - and when you didn't have school, hed either bring you with him to Bonko’s Garage, where he works as an amazing mechanic, or, rarely, let you stay home alone - having his friends check in on you from time to time
You didn't mind being home alone, you just did your homework and watched tv when you had to be - and you liked being at the Garage with Fonz, Fonz always rambling to you about car and motorcycle parts, which you understood maybe 20% of it, but you did find it interesting, and he taught you how to help him out from time to time
You were a bit of a straight A’s student - unlike how Fonz had been before he dropped out. And so, he called you a nerd in the most loving way.

You were sitting in your room at your desk, working on some homework one of your teachers gave you to do over the weekend, because of course your least favorite teacher had to ruin your weekend
You had been sitting there FOR HOURS, Fonz having gotten home pretty around the same time
You had been so focused on your work, that eventually, you heard a knock on your doorframe, you turn your head to see a very impatient Fonz - who had apparently had been calling your name for a few minutes now
”Kid. I've been callin’ you for minutes.. Here's the deal: you got two choices here, You come eat on yer own, or, I will personally carry you out like a sack o’ potatoes.” Fonz says simply, crossing his arms, then adding ”Either way? Yer sittin’ at the table. Dinner’s gettin’ cold, and that’s a crime against food, so move it, yeah?”
