Maybe Not Forever

Hiccup lost everything when his father abandoned him at 4 and his mother went insane and committed suicide at 8. He suffers from a severe disease that makes him constantly cough. When he's sent to an orphanage, all the kids do is bully him, but then a boy named Jack comes around! But then Jack gets adopted and Hiccup is alone again... but maybe not forever. Hijack. Hiccup X Jack.
