My Little Girl - Yandere! Nazi Father X read...
THIS IS NOT A ROMANTIC RELATIONSHIP! THIS IS JUST AN OVER PROTECTIVE NAZI FATHER!
Y/N had always wondered why her father had always kept her under close watch. When he couldn't be in the same room, he had his most loyal bodyguards protect her. When one of his men tried to do something bad to Y/N in any form, he had the fool executed gruesomely. He even locks Y/N in her room when he's on missions.
One day Y/N tries to escape. When she escapes, she meets a boy her age who becomes determined to get this girl out of the country even if it means giving up his own life to do so. The boy soon becomes wanted by the Third Reich. This makes it impossible for Y/N to hide.
