Ereri (Eren X Levi) Psychotic Love

I do not own Attack on Titan or any characters in this story!!!
Warning: Graphic Violence, Cursing (No duh), and Triggering Psychological Disorders

Levi never was one to play well with others, whether on the playground as a kid or at work as an adult. His parents were worried for a while but grew to just accept him as different from other kids. Was that their first mistake? Was that what drove Levi to where he was now?

Eren was always second best behind his 'sister' Mikasa. He was loud, obnoxious, but still got his work done and graduated from High school with Mikasa. He wanted to show his mom and dad that he could be just as good as Mikasa and even better. He went into the detective branch of the Wall Rose Police Department and became his departments lead weapon. He recently got put on what people are saying the toughest case they've seen. He looked through the suspects list and saw someone strangely similar. Levi Ackerman. Where did he see him before and why did that name sound and look so familiar?

"Are you scared Jaeger?"
"No."
"And why not?"
"Because I know you can't do shit."
