You control the strings to my heart {Marionette x OC}

Hey guys, as you can tell, this is a fan fiction about the Marionette. I've always liked this character, and I've noticed there aren't a lot of stories like this about him, so I figured I would do this! I will try my best with this, and keep in mind this is my first fan fiction! Also, I apologize ahead of time for grammatical mistakes and spelling mistakes. My iPod is stupid. This is my second time writing this because of it!

Catherine, or Cat, always loved Freddy Fazbear's Pizzeria, and always went there as a child. Even after they replaced the animatronics and re-did the restaurant, she still went. She actually liked the animatronics more, especially the Marionette. She had so many good memories there, especially with him. So 10 years later 15 year old Cat saw an ad in the newspaper for
the pizzeria, she knew she needed the job. She needed a job anyways. She thought it'd be a normal job, but oh was she wrong...
