Dust!Sans x Reader

It was all good. Sans and I were punning like usual, annoying Papyrus.  He had asked me to be his sweetheart, and I gladly accepted. He's been acting strange lately, though.

I look over to Papyrus. "I'm going to follow him," I say. I follow him to the Ruins and a goat lady lets him inside. Suddenly, I see a human. Sans strikes, and the goat lady gets dusted. I gasp and run so he can't see me.

As I follow Sans, I watch him kill more and more innocent monsters before that human follows him. The human is killing as well. Why is he doing this? Why is Sans going insane!?!

I run up, to a big mound of dust with a red scarf on this. "They made me so this," a low, smooth voice says. "I'M GONNA KILL THEM!" He yells, being none other than Sans. "Don't worry Papyrus, soon you'll be back and they'll be gone."

I take Papyrus's scarf and tie it around my neck. He was like a brother to me, how could Sans kill him? His own brother!

For a break, I go to Grillby's, which is cleaned out, only Grillby inside. "We all thought he was joking...but his eyes gave it away...he's insane," Grillby says. I sigh and lay my head on the counter.

"What should I do, Grillbz?" I ask. He looks at me. "Stay away from the two of them."

Shoot, is that the human? They walk in. "I can tell you're like him," Grillby says to them before they leave. I sigh. "Papyrus is gone, and everyone else is, and Undyne and Alphys and Mettaton and everyone is gonna die and Sans is an insane killer..."

Grillby pats my head. "It'll all be over soon," he says. I smile weakly. "You sound like the river man." He smiles. "If I was, I would have the risk of dying every day at work."

I giggle. "You always know how to make me feel better, Grillbz. Thanks for everything, don't die." He nods. "Same for you. Stay safe," he says before I wave and exit.

Then I run to judgment hall where Sans is fighting the human. "Heh, go ahead and hit me, I've gained so much LV that it won't kill me. Soon, you'll be eradicated and I can live happily with my bro and Y/N."

Wait, he's doing this for me and Paps? I'm so confused! Sans allows the human to hit him, and I can tell it'll take one final blow to finish him off. I jump in front of him before he can get hit.

"Y-Y/N!? NO!" The human giggles and stabs Sans as well while his guard's down. "W-well, I'll just use everything I've learned now in the next timeline!"

The human smiles evilly. "W-what? You're...erasing my memories! No!" He smiles weakly at me. "I'm sorry
Y/N, I've failed you and Paps. I love you both so much."

Sans then looks to the human. "Can you at least tell me how many times before-" The human finishes him, and kills me too.

At least we're all together now and in a better place.

But seriously though, I really need suggestions, please comment!
