Alternate universe so I have a lot more to work with, and so that I can be completely original...well aside from the basis idea
Also, if you aren't ok with death, suicidal thoughts, dark and cheesy love and whatnot, why are you even reading this. There. That's the warning.
Levi is the typical Yandere. He had no emotions until he saw Eren. Then he found his one and only purpose. Besides cleaning of course (yes I'm keeping that in, it's a crucial part of his personality).
Eren, however, is completely and utterly scared of every type of love, or at least scarred. The only love he can handle is that from his sister, and best friend. Other than that, he refuses to open up to anyone for fear of getting hurt. And turning into that monster...
If I'm not original and this has been done before, I apologize.

On the outside, you are pitied for being cursed with the inability to speak. Little did they know, you're carrying heavier aspects of yourself from the inside.
Disclaimer: Though the references are there, you are not completely an AOT version of Nezuko!!! Also I do not own the Attack on Titan franchise and they belong to their rightful owners.
Also, this book contains major spoilers to the AOT Franchise; DON'T read if you don't want spoilers.
