YandereTale

I dunno if this AU is already made by other people. Just thought it'd make sense if Sans is a yandere XD

"SANS! STOP!" (name) heard Papyrus yell. They jolted out of bed and immediately ran to where the noise came from. With their hair disheveled and baggy clothes barely hanging onto their shoulder, (name) called out to sans.

"sans! What are you doing!?" They jumped between him and Papyrus before sans could land an attack. "(name)-chan, please go back to your room. my brother and i are discussing an important—"

"(NAME)-CHAN! PLEASE MAKE MY BROTHER FEEL BETTER! HE'S BEEN LIKE THIS SINCE WE HAD A DATE.. HE'S MAD.. HE'S NOT WELL!" Papyrus sobbed and they quickly comforted the skeleton with a warm hug. This only made sans even more furious. His white pinpricks were gone now and his skull was quickly turning bright blue.

"What's wrong with you? He's your brother— AH! SANS!" He got a hold of their soul and its color turned to blue. "stay away." He made (name) stick to the ceiling. "sans! What did you do to my clothes?" Within a blink, their clothes were replaced with sans'.

"isn't it obvious, (name)-chan? i have to fight in style." His right eye was now smoking with a blue neon light. Papyrus face expressed pure fright when he saw this and his bones started to make strange sounds. "i can tell that you are now rattling in fear." He chuckled darkly.

(Name) became furious and their determination overpowered sans' magic.

"No one is fighting on my watch. Don't go Yandere on me about this, sans. He's your brother and it's your job to keep him safe. In fact, it's the only job you're good at and also the only one you're actually making an effort to do.

A/N: or is he? mwahaha :(

Well, until now. Worry not, Paps is safe under my watch until you untangle those crazy strings in your skull." They took Paps' hand and sans gaze refused to let go of the sight.

"what's a yandere?" He clenched his hands as he prepared for a secret attack. "Don't try anything weird in my presence sans." They sighed.

"I'm not happy with this.. You being like this. I hope you get well soon." They shot sans a cold hard stare before walking away.

sans was heartbroken. He didn't want to make his love sad and worse, disappointed.. at him. He only wanted to protect them from him.

*As he watches the two march out of the house, Papyrus sends him a message only the two of them can hear..

Papyrus glanced back at sans shortly. With his 'face' still stained with his orange-ish tears, he gave sans an evil grin.

"!!"

"..."

"...bastard."

for (name's) comfort, i'm gonna kill him.. another time.
