I feel i know what shes going to do which might work but its only a thought because it really depends on the bastards reaction. Oh please do what i hope for!
A girl gets pregnate. Her family sucks. The guy who got her pregnate sucked at first. The guys mom or step mom tried to get rid of the baby. And the girls shit father is the reason the guys father died because he was hit by his truck. All I remember.
The plot is a Princess doesn't want to marry a Prince from a Dark Kingdom or something, so her brother takes her place and pretends to be her and marries the Prince. It's a short story and the brother and the prince stay together in the end. It was so cute.
I love you Grandpa!
