You can be king again (King x Ban)

I was hit by the idea to write this by the song 'you can be king again'

King lost his whole family at a very young age not all at once though.
His mother, father and younger sister all died in a house fire that King was the only one lucky enough to survive, but he wasn't unscathed he was then given over to his only living family left, his aunt and uncle but yet again tragedy struk when both of them were killed in in a horific car accident when he was in nurysery.
He was then put in the system as a foster/adoption case but soon enough a that seemed nice at the time had taken a liking to
They had two kids already one was in university so wasn't there a lot but he visited when her could, which wasnt very often, there other kid was just a year or two older than him her name was Laura and it was her goal un life to make sure his was hell.
This was all until King met Ban, and his life became some what liveable
