Heya guys and welcome to my first Undertale fanfic.

Now there are a few things I would like to mention before starting this fic.

1. This is a two-shot story, so there is only going to be two chapters.

2. I know a lot of people like to argue about Frisk's gender, whether their non-binary or not, but in this story Frisk is a girl.

3. The pairings in this story may contain a one-sided Mettaton/Frisk and a hinted (but mostly platonic) Sans/Frisk.

4. Frisk is fourteen years old, which is still a young age to pair her with an adult, but I find it less creepy to have her at this age than to have her as a child under the age of 12.

If you have a problem with any of these points, I recommend you don't read. If you do read it, please be respectful and don't give my any flack.

~The Show Must go on~

Chapter 1

It was evening and Frisk had decided to go to the new MTT Resort, which was built on the surface four years ago after the barrier was broken. She had received an invitation from Sans to meet him on the MTT stage at 7:00pm, but Frisk wondered why her skeletal friend would want to meet her at a place like that. Normally Sans would invite her to Grillby's, his house, or a random restaurant, but the stage in the MTT Resort seemed to be out of the blue. Once Frisk had entered the exact location, she looked around to see that the lights were out and that the stage was empty.

"Hello, is anyone here?" she called out as she walked in the middle of the platform. Frisk kept looking around in this dark area, but she couldn't see anything. "Sans, if this is some kind of joke I am going back home!"

She kept searching the area for her skeletal friend, but there was still no sign of him. Frisk was almost ready to give up, but before she could leave, she heard a voice that echoed throughout the room and it spoke directly at her.

"Why, hello Frisk darling~ I am SO glad have you on my stage~"

Frisk recognized that voice, but it didn't belong to Sans. She only knew one guy who had a robotic and flamboyant accent, and that guy wasn't her skeletal friend. Suddenly, the area was engulfed by clouds of dried ice and Frisk could hardly see a thing. She than heard a thump that came from behind her, so she looked back to see what was going on. Before Frisk's eyes, a couple of spotlights turned on to the spot where that noise came from and she had seen a human-like figure within the fog. This mysterious character was doing a dramatic landing pose, but then he got up on his feet and stood there in a fabulous way.

"M-Mettaton?" Frisk said in a bewildered tone.

"Why yes darling, it is I~" the robotic figure replied. "So Frisk darling, I'd seen you had gotten my invitation."

"W-wha? You're the one who sent me this invitation?!" Frisk exclaimed in shock. "But why was it addressed by Sans?"

"Just to make a dramatic scene, darling~ I knew that you liked to hang out with that skeleton, so I'd signed his name on the invitation, so you would think it came from him. Also, why would you think a lazybones like him would invite you on a stage like this?"

Frisk had slapped herself in the head like she should've known that something was up. She then looked up to Mettaton and asked, "So, what did you invite me here for?"

The dried ice began to clear out so that Frisk could clearly see Mettaton.

"Well, Frisk darling, I had missed having you on my show. You helped me gain so many viewers on our last performance together and I was hoping you could join me on another show." Mettaton had walked up and leaned his body towards Frisk while he put one hand on her shoulder. "So, what do you say, darling? Would you join me for another show?"

Frisk had given it some thought if she should accept the flamboyant robot's offer or decline. She remembered back in the past four years when she was a part of Mettaton's shows and she recalled that the robot nearly killed her. Although she had nearly died during that time, she couldn't lie about the fun she had when she performed on stage. Frisk also didn't have any special plans for tonight, and since she was already at the MTT Resort stage, she didn't want coming here be a complete waste of time. Frisk looked up at Mettaton with a soft smile and replied, "Sure Metteton, I would love to join you for another show."

Mettaton's smile had grew larger and said, "Well, then let's get this show on the road."

With that said, the middle stage layer began to shake before it rose up. Frisk was trying to regain her balance as the stage moved, but Mettaton just stood there with his arms crossed like it was nothing. After the platform stopped, Frisk had already fallen on her knees and her hands were place down in front of her. Suddenly the song "Death by Glamour" was played in the background and Mettaton began to dance.

"Well darling, aren't you going to get up? The ratings aren't going to go up if you're down on the floor like that~ Perhaps I should give you some motivation~"

With that said Mettaton had charged at Frisk and attempted to kick her. The teenage girl only had a few seconds to react. She looked up and saw that Mettaton was charging straight at her, she rolled out of the way to dodge his attack. As Frisk was trying her best to get back on her feet, Mettaton attempted to kick her again. The teenaged girl again rolled to the side before she could get hit, but Mettaton only missed her by a hair. He didn't stop attacking the teenaged girl, so he kept attempting to kick her until she got up. Frisk kept rolling away from his attacks, and after a few kicks, Frisk had jumped back, while she landed on her hands. Mettaton send one more kick Frisk's way, before she could flip back. When Frisk landed on her feet, she put one leg behind her, leaned her body back, put on a stage smile and flashed a peace sign to her left eye. The crowd had applauded her pose as the ratings went up to fifty.

"Not bad darling, but will you survive my next attack?" Mettaton asked before he charged at her.

Frisk once again only had a few seconds to react. When she looked to Mettaton's direction, she narrowly dodged to the side, before he could punch her. Mettaton, however, was not going to give up his attack. He then threw a few kick at the teenager's direction, while Frisk did her best to move out of the way. She kept dodging the attacks thrown at her, but then Mettaton did something, which took her off-guard. The robot reached out to grab Frisk's left wrist and pulled her closer to him. He used his free arm to wrap around her back and dipped her back slowly. Mettaton's face was three inches close to Frisk's face, and the girl gave his a puzzled expression.

"How about we stop the fighting and cut to the dance, shall we?" He said as he twirled Frisk out to the side and pulled her back into an embrace.

Mettaton then began to lead a three step dance with his fancy legs and Frisk tried her best to follow his movements. She did have some difficulties following through with the robot's patterns, but she wasn't doing too badly. Frisk did have some dancing experience when she was younger, but she never considered herself to be a professional. The teen was however starting to get used to Mettaton's dancing style. After a few seconds, Mettaton twirled her around in one place, and she spun awkwardly, before they went back to their waltz position. While Frisk was still baffled about the dance, she had almost forgotten that she was on a show. The point on being on a MTT show was to raise ratings, so she thought that she needed to wow the audience more. As the music began to speed up, Frisk stepped up her game as she worked with her legs. Mettaton had twirled her around in one place again, but this time she had wounded elegantly. They were back in the waltz position and they began to do the three step dance. Frisk was doing amazingly enough that she could keep up with Mettaton.

"Not bad, darling~ but can you keep up with my next moves?" The robot asked.

Frisk was once again baffled as she wondered what was going to happen next. Mettaton twirled her out rapidly fast to the side, without letting go of her hand, then he pulled her back. He held her very close to his chest with his free arm and he was staring deeply into her eyes. Their faces were only three inches apart and Frisk began to blush intensely in embarrassment. Mettaton led the dance by moving forward, while Frisk tried to keep up. The robot twirled the girl out to the side again, and then he pulled her back. Once Frisk was back into his arms, he dipped her down. Mettaton had one arm was supporting her back while the other was grabbing onto her left leg. While he held Frisk in that position, he lifted her up above his head, while the girl lifted her right arm to reach the sky. Mettaton then spread leg out and started to spin around. While he was twirling he was also lowering Frisk down, until he was holding her bridal style. Once Frisk was low enough that her right foot could touch the ground, Mettaton stopped spinning. His face was once again three inches closer to her face, while he kept one arm around her back and the other on her left leg. Mettaton still had his right leg sticking out, while Frisk had both her arms reaching the ceiling.

The audience had filled the area with their cheers and applause. Many of them were chanting Mettaton's name and some of them were freaking out like idiots. Mettaton had gently released Frisk left leg and then he stood himself up, while he kept one arm around the girl's back.

"Well, Frisk darling, it has been a pleasure of having you on my show. You help me gain so many viewers and the ratings are now off the chart~" The robot said.

He then moved his right arm from Frisk's back and rested his hand on her left shoulder. Mettaton had also kept one arm behind his back, which made the girl curious to what was going on.

"Well, my darling, since you helped me gain so many viewer-" Before Mettaton could finish his sentence; he kneeled down on one leg and pulled out a small box from behind his back. He opened the box in front of Frisk, which revealed a golden ring with a sparkling diamond on it. "How would you like to be my bride?"

That question completely caught Frisk off-guard. Her jaw had dropped, her eyes had widened, and her face was redder than a tomato. Her body was paralysed in shock and before she could say anything, Mettaton deviously grabbed her left hand and side the ring onto her ring finger.

"I'll take that silence as a yes." He had smirked darkly.

Meanwhile at the skeleton bros place on the surface, Papyrus was sitting on the green couch in the living room, while he watched Mettaton's show on television. A few seconds later, his older brother, Sans, had come back home from one of his jobs. He was a bit weary when he came in, but he was also calm and relaxed. Sans turned his head to his younger brother, who was still watching TV and greeted, "heya bro, what'cha watchin?"

"SHUSH! PIPE DOWN, SANS! I AM TRYING TO WATCH THE HUMAN ON METTATON'S SHOW." Papyrus retorted.

Sans then stared up at the television screen and saw that Mettaton had one arm around Frisk's body. The white pinpricks in his eye sockets had disappeared as he looked down at the girl's face. Her face was beat red and she wasn't smiling. Her lips were trembling and her eyes were wide. Sans could already tell that Frisk wasn't happy.

"Now that is our show for today, darlings~ Tune in next time to see the marriage between Frisk and I~" Mettaton announced.

Sans stood there like a statue after Mettaton had made that outro. The minute that he heard that Frisk was getting married to that robot filled him up with frustration.

"SANS, IS SOMETHING THE MATTER?" Papyrus asked in a concerned tone.

After a few seconds, a glowing yellow and cyan eye had flashed within Sans's left eye socket, while he was clenching his fists.

"Mettaton, you are gonna have a bad time!"

So, what do you think would happen next? Will Frisk and Mettaton get married or will Sans be able to stop the marriage? The answer to that question would reveal in the next chapter.

Feel free to leave a review if you so choose. I will accept constructive criticism, but don't be giving me hateful comments.
