yandere us! sans x neko reader

You lived in the underground for a xouple of years now.

You have grown a liking to the small place, and everyone seemed nice.

But there was one problem.

You noticed that some of your close monster friends dissapeared,  and later on found dead.

This made your (f / c ) fur stand on edge.

Your ears flatten down wondering,  if your the reason that all these monsters were disappearing?

But at least you had your two best friends.

Two beloved skeleton brothers,  the older one papyrus,  and the younger one sans.

Paps was like a big brother to you and was always there to comfort you.

And sans was like anyone's little brother. He was like an adorable little cinnamon roll.

But secretly, you had an innocent crush on sans, and you were going to tell him eventually, when the time was right.

You were heading back home when you bumped into nice cream guy.

"Oh, hey Nc!" You called out cheerfully.

He looked up and shrugged,  and turned his head the other way to hide a small blush.

You walked up to him and began to start a conversation.

"I don't know who's been doing this but I hope that they have the heart to stop." You said after telling Nc guy about the murders that have been happening.

He scoffed. "Yeah, well I guess, I wouldn't care eaither way."

You sighed and were abput to head off when nice cream guy grab ahold of your hand.

You paused and gave him a confused look.

"Hey uh, ( y / n ), I've been wondering... I have the day off tomorrow and I was hoping that you and I can, umm... I don't know, go out sometime? " he asked nervously.

Your mouth was wide open. Even though you didn't like Nc guy like that, it would be rude to turn him down, so you you accepted happily.

"Sure, we can meet up later on tomorrow in the evening!  How does that sound? "You replied eagerly.

He tried to say something, but couldn't find the words so he gave out a simple nod and watched you go off.

But little did both of you know, that someone was watching you not to far away.

"*growl* ( y / n ) is mine not yours!" He snarled.

He waited for you to leave before walking up to nice cream guy.

"Heya Nc!" He said awfully cheery.

He turned around and gave a small wave.

"What's up blueberry?" He said turning his head around not really caring.

Blue's eyes twitched a bit, but he was trying hard not to break just yet.

"I heard that you and my future g- I mean ( y / n ) are going o-out." He choked on thise last words trying to force a smile.

He nodded and blished slightly, which made blue grit his teeth.

"W-well, I have a gift for you b u d d y..." he spoke softly as he was walking towards him.

And before nice cream could react, sans took out the knife he was hiding behind his back and stabbed him right in the chest.

Nc looked at him with horror as sans was laughing maniacly.
