I'm Abbycat and Goku is my dad.
I was really not into the idea of having someone take care of me for a looong time. I thought it would make people take me less seriously, especially as a syskid.
But Goku...was in the system from really early on. He was one of my first "imaginary friends" or "friends on my head" I called them, before we realized we were a system, and your "imaginary friends" holding full conversations with you wasn't exactly "normal."
I know it's cheesy and corny, but Goku was always there when I was angry at how life was going, or sad about my (bio) dad's back injury, or upset about the abuse I was going through.
And he just recently woke up again and...it was just...so much.
Goku is my dad now. He probably was back then, too, but it's official now, I guess.
