[Undertale] Sans X Reader - Repeat, Eternally

Chapter 16 ~ Monsters, Of The Glamour Run

How did you find yourself in this situation? Here you were, sinking into a pool of endless jello-y darkness. Gaster was beside you, and almost fully consumed by the jello.

"G-Gaster! Hold on!"

"This is why I suggest you should never allow Papyrus to cook." Gaster muttered. "I choose facts and truth over lies. I am a scientist. But never, in my years, have I seen someone do something this stupid."

6 Hours Before Jellopocalypse

"M-Mettaton?" You asked, when he burst through a window with Napstablook in tow.

"IT IS I, DAAAAAAAAAAAAAARLING!~" He swept you up in his robotic arms and nuzzled you. You felt a shock. "Oops, my bad!~ I do that to humans when my excitement reaches fantastic levels.~" He laughed, that fabulous kind of laugh where one would throw back their head and laugh like they had not a single care in the world.

"Mettaton, what are you doing here?" You asked, sheepishly. You wanted to be nice, but you weren't in the mood.

"Well, darling... I heard you escaped! And I just had to start a Glamour Run with YOU as our guest of honor."

"A...Glamour Run?"

"A Glamour Run is simple. You take what you love about yourself, your best skill and the thing you're most proud of, multiply it by 700, and then show it off to the world! Also, I need you to sign on this dotted line that says I am in no way responsible for any national landmarks you may destroy whether it be with spaghetti or otherwise." He was talking so fast that you could barely process what he was saying, but by the time he was done, you had signed on the dotted line and completed the entire forum. "Papyrus is entering with his cooking skills, as usual, but I banned him from doing spaghetti again, so he's got some kind of powder. It comes in boxes. He has about 800 of them. Meanwhile, Undyne is entering for her strength yet again... Toriel is entering her cooking, Asriel is entering his drawing, Frisk is entering their social skills, mostly flirting, Sans is entering for laziness, and Asgore is entering for singing. Asgore and Toriel are back together, by the way."

You sat there, confused.

"Ah, and you're entering for...heartbreak?"

That snapped you back to reality.

There was a question in front of you.

What is currently your greatest ability?: Heartbreak

How embarrassing. You attempted to erase it, but Metatton took the paper.

"Amazing! How tender! How....ratelicious! Yes, this will be a hit! And you get to talk about your feelings in front of thousands!"

Damn.

"Not only that, but Sans will be there!"

Damn.

"Everyone will be watching!"

DAMN.

"I'd like to withdraw my entry!" You panicked, tripping and crashing to the floor. Mettaton laughed.

"Hahaha, nope." With that, he blasted out of the house with his rocket-boot-feet things. A giant hole was left in your ceiling. You slumped to the ground, and Asgore broke down your door. Toriel rushed in, holding a frying pan in a fighting stance.

"_________! Child! We heard the noises, are you okay?!" Toriel's eyes trailed to the hole. Her mouth dropped open, and the frying pan dropped to the floor. Asgore showed the same look of surprise.

"Uh...Mettaton paid me a visit."

"... A-Asgore, darling... can you please fix the roof?" Toriel stuttered.

"Of course, my l-love." Both seemed scared of Mettaton's flamboyant nature. "Maybe we should start asking to meet Mettaton elsewhere... he destroys our things more than Undyne does."

"Wonderful idea, dear." Toriel turned to you, her regal demeanor returning. She gave you a warm smile. "Shall I make you some lunch while we wait?"

You nodded.

Down in the kitchen, Toriel was making some sort of monster recipie for lunch. She sighed.

"I have been a mother of four children, ____. I know there is something wrong. Must I find out on my own?" Toriel turned to you.

"I...uh..." You couldn't find anything to say in response. Toriel's intuition was spot-on.

"It's about Sans, isn't it?" Toriel asked. Wow, her intuition was more than spot-on.

"Sans proposed to a human. Me and Undyne were on our way to Grillby's new place, and..."

Toriel gasped, and a dish slipped from her hands and crashed to the floor. "W...what? Sans is getting married?"

"It's funny because it's like a scene from a movie. A really cliché movie, but a movie nontheless."

"This is in no way cliché, child. You saved Sans' life, he gave up on you, and he has the nerve to propose in front of you?! I'm going to drop by for a visit tonight."

"No! You can't! It'll just make things worse. Besides, this is the future he chose!" You protested. "This is what Sans wants."

"And what about what you want?"

"I'm not part of their equation. What I want doesn't matter."

Toriel went silent for the rest of lunch.

Don't worry. The top is just a little of what's to come.

GASTER RETURNS?!
