Mine (Yandere! Levi x oc)

Part 1

I stood there petrified at the sight before me. Bodies scattered throughout the hallway; bathing in their own blood.  Once again I heard the whimpering sound. I try following it, but it's silenced by a gun shot. I quickly ran to the source of the sound only to find it was coming from the library.

I slowly open the door and look inside. The shooter isn't inside, but about five of his victims are. Like the ones in the hallway,  they are lying in a pool of their blood.

I try not to throw up when I realized one of the victims lying before me is Annie Leonhart. "Annie" I whispered as I felt the tears fall.

Sure we didn't talk anymore because of this feud between our group,  but she was still once someone I called a friend.

Another round of gunshots went off. This time, it was right outside the library doors.  I carefully walked to the other side of the room and opened the door.  Waiting for me was another set of bodies. This time, they were teachers.  More specifically,  Mike, Ms.Zoe, and Mr. Smith.  I slowly walked to them and kneeled next to Mr . Smith who I noticed was still breathing. "Sanae" he whispered.  I snapped my head up to look at him. "Mr . Smith,  you're-!" I exclaimed before being cut off. "You have to get out. He'll come after you next" he warned. " W-wait! Who's doing this?!" I cried. He didn't say anything,  he just pointed down the hall. With that, he took his last breath and died.

I stood up and made my way down the hall towards the science wing.  I jumped when I heard a shot. I composed myself and ran towards the sound.  I wasn't going to let them get away with this!

I got to the science wing and what I saw would scar me for the rest of my life: Levi holding a gun to Marco Bodt's head, blood was splattered on Levi's face and clothes, and he wore the most crazed grin I had ever seen. "Levi, why...?" I whispered as tears poured out of my blue eyes.

His cold steel eyes  bore into mine. "Why?" he asked with a smirk. He then laughed, but it wasn't like his usual laughs. It was more sinister. "Why did you break up with me?" he retorted with that usual bored look.
