Does anyone here know the back story of this song?

Is this his personal story or is this someone he knew?
I personally think that this is his story given that the boy is blond haired like he is.

1. This is all I could find with a quick search:

Written by Faster Pussycat frontman Taime Downe and guitarist Greg Steele, "House of Pain" is about Downe's father, who wasn't there for him:

There's no one home
In my house of pain

Downe's dad was a guitar player who brought rock music into the household, which according to Taime was the only contribution his dad made to his career. Taime was named after his father (Gustave), but rejected it, going with a childhood nickname because he didn't want to give his father any credit.
