[Undertale] Sans X Reader - Repeat, Eternally

Chapter 18 ~ You, Of Dramatics

WOOOO! NEW RELATIONSHIP!
He's gay. I'm pansexual gender fluid.
I'm actually female in body, but to him I'm both or neither. ♡♡♡♡
He's an absolute SWEETHEART!
I like him so much ;u;

You got out of the car, staring at the large building. You saw a couple more cars pull up at the same time. Out of one, came Undyne and Alphys. Alphys looked absolutely strained, as if all the life had been drained out of her. It almost broke your DETERMINATION.

From the other car, came lesser dog and greater dog.

Almost every monster you've ever met came out of different cars, but the one that drew your attention was fancy and bright red. Out of it came Papyrus, the woman you had seen with Sans... and Sans himself.

"WOWIE. SO, SHE'LL BE LIKE MY NEW SISTER?" The nail inside your heart drove itself deeper.

"Yeah, Pap. She's gonna be moving in with us."

"OH BOY, PENELOPE, IT'LL BE JUST LIKE AN ETERNAL SLEEPOVER!"

"Well, I'll be happy to." Penelope said.

Sans saw me, and stopped cold. His expression became one of absolute shock.

You wanted to run. To turn away.

"Sans? Are you okay?" Penelope turned to where I was standing, staring at me. "Is... this person someone you know?"

Papyrus, of course, turned to me as well.

"_..._______..." He stuttered. "BUT YOU... YOU WERE GONE FOREVER... SANS SAID THAT YOU'D NEVER COME BACK."

"Well, Sans is a liar." You say, joyfully. You wanted Sans to feel every bit of pain you had felt. Everything you had endured. You knew it was wrong to want it, but it felt so good.

Were you really any better than Chara?

You didn't care.

"Sans...?" Penelope asked.

"Don't worry, Penelope." Sans said. "She's nobody. Papyrus is probably just mistaking her for someone- I've never met her in my life." He took Penelope's hand, and began to guide her away.

"So now I don't exist?"

Sans stopped.

"SO NOW WE'VE NEVER MET?!"

His grip on Penelope's hand tightened.

"Do you know what I endured in Mount Ebbot? The grasping loneliness? The feeling of my sanity slowly fading away?! Do you know what kept me alive?! Kept me hoping? Gave me DETERMINATION?!" You scream. "The thought that my friends... my loved ones.. would come to save me! Do you know how I felt once I knew I was abandoned?"

Your eyes were filled with tears. Everyone, everything felt alien.

"I hate you, Sans Font. I hate you, and you'll never change that. I'll hate your dusty bones until they become artifacts in a museum!" Your voice progressively got louder, even though all Sans was doing was listening. He may not be looking at you, but he was hearing every word. "You abandoned me when I needed you most. You think that humans are bad? Just wait until you've hurt one of us. We will do anything to even the playing field. I... I don't even know who I am or who I was. Everything is jumbled. I don't care how, but I will make you PAY." You hissed.

"Now this is uncalled for." Penelope stepped towards you, but Sans grabbed her hand. "No, Sans, this person is being rude to you for no reason. I'm not going to let that slide!"

"Really now?" You began to laugh. "Then why not ask Sans why I'm being so rude? Would you still love him if you knew the truth?"

You couldn't control yourself. Everything was crashing down around you, and furry paws scooped you up. Papyrus looked like he was about to cry.

You felt like you were about to cry.

"Come on. Let's go, Child." Toriel smiled down at you. "We don't need to keep the company of bonetrayers."

You couldn't help it. You began to giggle. It was so out of character for Toriel to call someone out like that, but you knew she was just as angry at Sans as you were. Toriel carried you to the building, shielding you from the curious, prying eyes of monsters.

Sans' eyesockets were completely black, and his grip on Penelope's hand slipped. He didn't even want to look at her. All of this made him sick.

"Sans, what's wrong? Don't let some girl get to you. You always have me."

But he didn't want her.

I'm so sorry that it has been like 3 chapters before the Glamour Run has actually started but there were some things I wanted you to see, like the way humans treat monsters and the tension between you and Sans. Even if you wouldn't feel this way, there is a perfectly good explanation as to why you are feeling like that right now.
Is Gaster the only one returning? ;)
