Fatal Insanity (Jeff The Killer X Reader)

You and Jeff had been best friends and neighbors since you were both little and basically grew up together, until you almost turned thirteen and moved away to a new town.
Crying inside knowing you would never see him again, but that all changed a year later, when you had found out that him and his family were moving into the same town and neighborhood as you.
Overall, you were happy that you could hang out with your best friend again, like old times. Though, you never expected to have feelings for him since he was your best friend, but one thing that took a turn for the worst, and the one thing that never left you the same, was that your best friend.....
