Dont be fooled by the title. This story is pure fiction, your interpretation of the story is always correct. You can think of whatever you want, she can be a victim of war, slavery or whatever you want to. She can be just someone wth traumatic experiences in her life, a rough past. He can be her past.
She can be you, and he can be the thing or the one who broke you.
They can be anyone's and anything's as long as you let your imagination fly and I would like to hear your interpretation in the comments.
