You were from district 12, a girl that was taken to be used by the Capitol as entertainment before being thrown back to the slums.
Of course by the time you returned to your district, an uprising was starting, the Peace Keepers becoming more brutal and dangerous as the people of the districts tried to rebel.
It was rough. You were either working and running back to your house avoiding the Peace Keepers. Especially as a woman.
Coriolanus Snow is a Peace Keeper. After being caught cheating as a mentor in the Hunger Games, he was sent to the districts to serve as punishment. That's how he met you.
After being tortured, beat, and many other horrible things done to you by the Peace Keepers, you constantly had nightmares. They woke you in the night, tears in your eyes and coated in sweat. Your screams could be heard by most of your neighbors, and especially the patrolling Peace Keepers.
After too many complaints, you were sent to stay in a cell in the Peace Keepers camp. Your nightmares continue, and you stay up sobbing alone in the darkness. That is, until Coriolanus is heading to his tent one night.
He hears your cries, and peeks into your cell.
