Sweet Serial Killer: Y/n X Yandere! Mickey Altieri

Chapter 1: The Prelude

A/N: I would like to thank foreveryoungspell for letting me write this reader insert. I hope you enjoy it! As far as updates go: I plan to do them weekly every Sunday. If for some reason, I cannot update by Sunday, I will post an A/N and the update will be held off until the following Sunday. This chapter is going to be a shorter than what I normally write, so I apologize. Criticism is welcome and I hope you all have a lovely day ❤️

A dingy apartment in New York, the summer of 1996:

Bloody boots slide off of Mickey's feet as he slips through the front door. Scratch marks run up and dow. Evidence of his latest kill. Not a great one by any means. At least for the cash it offered. His client was right. His target would be easy to find. Would have been nice however if he mentioned the part that she practically had claws for nails. He plopped down on the couch, letting out a sigh. Sure, the rush of the kill gave him the hit of adrenaline he so desperately desired, but there was no thrill in it. No greatness. He wasn't Jason running around in his hockey mask, slashing teenagers for the hell of it. He was just Mickey. Guns blazing and a knife for hire all for the sake of making a living. Soon, he wouldn't have to do this though. Taking meaningless hits for small cash. He'd be killing for meaning. He'd be the one to finally kill the final girl.

The phone rings.

He wasn't exactly in the mood to talk but duty calls as they say. He let out a huff of frustration as he answered the phone. "God fucking damn it....Hello?...No, not yet..Don't get your panties in a bunch yet, Deb! Information like this takes time. It's not exactly easy to get intel on a high schooler with no public records. The cops classify documents, you know." He rolled his eyes as his backer scolded him.

"We don't exactly have all the time in the world, Mickey. Open enrollments aren't always as they seem to be. College Admissions have to stop taking applicants at a certain date before the semester start. And need I not remind you, Sidney needs to die. The sooner, the better."

"Yeah well, however much time I need is how long it'll take. Plans like this take time to develop and need to be handled delicately." Mickey muttered a few curses under his breath as he got on the computer. "Let's see if it's our lucky day."

"For your sake, I hope so."

He laughed at her ignorance as he scrolled through the dark web forum. There were various ads for employment all over. Women offering small some of cash in exchange for the death of their husbands. Bigger serial killers posting their latest accomplishments. It was something he'd normally consider and take in with admiration, but now wasn't the time. He finally reached the bottom of the screen and found what he was looking for.

MESSAGES: ONE UNREAD

Mickey's ears almost pricked up with excitement as he clicked on the message.

"Well?" Deb asked from the other end. "Did they get back to you?"

He smirked much like an unhinged madman, trying not to scream with excitement as he spoke into the phone. "Oh, they did."

"Well, what did they say? Where is the bitch going to school?"

"Deb, Deb, Deb... You don't understand. It's not just her. The whole gang is here." His eyes narrowed on a picture of Y/n. "And I have an idea...one that is gonna rock! Tell me everything there is to know about Y/n L/n."
