Upside-down

"Sooo you wanna go somewhere??" Frisk asked as she was skipping next to him. Sans was walking with his hands in his pockets and he smirked. 

"sure, buttercup. what do you have in mind?" Frisk shrugged. 

"Let's just get something to eat." She said. Sans shrugged. 

"sure." They both walked and started punning as they were going towards one of Grillby's establishments that were close by. They were also pretty sure he was there so why not? They entered the familiar bar and Frisk waved at Grillby. The human immediately returned the gesture as he was lighting a cocktail up on fire. They sat at the bar and Frisk span on the spinning stool. Sans chuckled. 

"we'll take the usual, grilbz." The human raised a brow at Sans and he frowned, looking away blushing. If Sans knew his friend he was sure as hell he caught onto Sans' plan. But everything got ruined- 

"Frisk!" She turned around and raised a brow. 

"Oh! Ralph! Hey." She said to a tiger monster. He sat down next to her and looked at Sans. 

"Oh! You're the human! Hey! I'm Ralph!" Sans looked at him unimpressed with a fake smile, but still shook his hand. 

"sans." He said, coldly. Frisk looked at Sans confused. He just looked away. 

"Anywayssss....What did you need, Ralph?" He smiled. 

"So, you know that formal dance? My sister keeps pressuring me to go with someone and it's pissing me off! Do me a favor and go with me..." He said, putting his hands together. Sans felt his soul shatter. What...?

"Oh! Umm...But what about..." She looked at Sans and made a face he couldn't read. Excuse me?! You're keeping secrets from him?! 

"....Can't come..." He muttered. Frisk sighed. 

"Fine. As long as your sister will leave you alone. But we're going as friends." Sans calmed down a bit however- Did he just lose his shot...? SHE SAID YES AND HE JUST LOST HIS SHOT- OH FOR FUCK'S SAKE!

"Oh THANK YOU FRISK! You're a life savior, you know?! Also, of course we're going as friends! You know why." She giggled. 

"No problem, Ralph. And yeah yeah, got it. Now then...We were just getting some food. You wanna--" Sans put a hand on her shoulder. 

"yeah. we were getting some food so could you like...you know." Ralph's eyes widened. 

"Oh...OH! OH GOD! hahahha! Sorry, my dude. I'll leave. See ya Frisk! Oh and don't forget about the project!" He said waving. Frisk waved back at him and turned to Sans with a small frown. 

"What was THAT?!" Sans grumbled something. 

"What...? Listen i can't understand when you're mum--" Grillby came and put down two burgers and two plates of fries. Frisk sighed and looked at Grillby with a smile. 

"Thanks, Grillbz." He nodded and smiled back at her. Frisk took some fries and then Sans saw his opportunity. He passed her the ketchup. 

"want some ketchup with that?" She sighed and giggled. She took the bottle and opened it. The cap fell of and the content fell on her fries. She snarled. Sans snorted and started laughing. She took his fries and hers and slammed them together. Sans watched with wide eyes as she shook the two baskets with fries and when she pulled them apart they had the perfect amount of ketchup on them. Sans eyes twinkled as she opened her golden eyes to look at her work proudly. 

"you goddess..." He said as he ate a fry and it was the perfect amount of ketchup on it. Frisk laughed. They both ate and joked around until she realized something. 

"Hey Grillby! Have you ever thought of hiring a DJ?? This would make a great bar club!" She said. Grillby and Sans and a few patrons looked at her in surprise. 

"You think?" Grillby asked. She smirked. 

"Hell yeah! Here, may i be the first one to mix at Grillby's? It's free!" Grillby's eyes widened and he smiled and nodded. Frisk looked at the corner where Grillby now set up a dj booth instead of the jukebox, which was playing pre-recorded music and it wasn't even something to really dance to. 

"you know how to mix?" Sans asked her. Frisk shrugged. 

"I got bored a lot. Learned a lot of stuff. Also Grillby...do you have anything that i could...you know.." She made a motion with her pinkie and thumb. Grillby chuckled and came with a shot of tequila. Sans frowned. 

"hold on--" She downed it. Sans stared in disbelief. 

"you're still recovering! frisk!" He said. She laughed at his worry. 

"It's fine. It's just one. You drink ketchup at Grillby's all the time." She said. Grillby hummed. 

"She has a point." Sans snarled at Grillby as he took her side. 

"don't! encourage her!" She laughed and jumped in the DJ booth. It was a bit old fashioned but she could work with this. She twirled the discs and then plugged her phone in. She decided a small mash-up was perfect. What better songs then Tkn by Rosalia, Mi Gente by J. Balvin and Tap in by Saweetie. She smirked. She started mixing. The patrons perked up. She set up the mix and jumped out and went over to Sans. 

"Sooo...ever danced before?" Sans spurted and choked on his drink. 

"t-the hell? of course i did but why are you--" She pulled him by the arm and made him get up. 

"Then dance with me!" He blinked in surprise as she started dancing like they weren't surrounded by people. But she had the moves, he had to admit. He hips and body synced perfectly to the song. Soon enough patrons were dancing and Frisk was waiting for Sans. He blushed and chuckled as he got up. 

"fine..." She beamed at him and he started trying to match her steps. His hands were on her hips and her tail was curling around his leg. They both laughed as they danced. Frisk apparently had the moves. And Sans wasn't a bad dancer himself. They quickly synced their moves. Patrons would stop and stare at them for a bit to admire them. Some even clapped and cheered. They parted as Frisk did a small solo. Sans laughed and pulled her back to him, bending her backwards. 

"You really have nice moves, huh Jagger?" he smirked and winked at her. 

"ya can't imagine sweetheart." She giggled and just as he was about to lean in, her phone started ringing. 

"Oh! Sorry, i need to go and return a book at the library! I didn't expect you to take that long! Sorry--" She got up and rushed out of the place. Then Sans let himself fall back on his stool between the dancing patrons. 

"Ouch." Grillby said. Sans snarled at the human with red hair. 

"yeah yeah...shut up..."

"She's WHAT?! WHO THE HELL IS RALPH??" Chara asked, in disbelief at the news. Asriel frowned. 

"I never heard her talk about any 'Ralph'." He added. Sans growled. 

"that's what pisses me off even more!" Papyrus gasped. 

"RALPH? AS IN RALPH HER GROUP PARTNER THAT SHE TALKED ABOUT ONCE?? DIDN'T SHE SAY HE WAS GAY??" Sans, Chara and Asriel turned to Papyrus with wide eyes. 

"HE'S GAY?!" They all asked, hope glimmering. 

"Who's gay?" Frisk asked as she stepped inside her living room. The four humans stiffened. 

"U-Ummm....Papyrus...?" Chara asked. Papyrus blushed a bit and shrugged. 

"IT IS TRUE." Frisk raised a brow but just shrugged and went over to the fridge, getting a soda can. 

"Welp...I'mma finish this and go out with Ralph to pick our outfits for the dance. The guy is so excited he is already thinking which eye color would go best with the dress he wants me to wear. Pfft-" She said as she opened the soda can, her tail doing a small wag from a side to the other. Papyrus raised a brow. 

"IS HE INTO FASHION??" Frisk smirked. 

"Every gay person is, isn't it?" She said as she walked away. Sans felt a huge weight getting lifted off of his shoulders. 

"THANKS GOD!" Sans said as he let his head fall backwards. Chara smacked him. 

"NEVER SCARE ME LIKE THAT AGAIN! For a second I actually thought my ship may sink!" Sans frowned, flushing. 

"your what now?" Asriel covered her mouth, chuckling awkwardly. 

"Ahahahah...don't mind her. She's crazy." Papyrus laughed and nodded. Sans rolled his eyes at them. 

"yeah no. i'm sleeping on this one..."

"Are you sure you aren't mad, Frisk...? I mean...That guy seemed to want to ask you to the dance..." Frisk giggled and nodded. 

"I don't think he was about to do that...He doesn't like me...I think.." She said, with a small frown. Ralph face-palmed. 

"Frisk, darling. As much as I love you, you're obliviously blind." She blinked in surprise and raised a brow. 

"What...??" Ralph chuckled. 

"I know that I asked you last week but the way he looked at you and at me? Frisk, you oblivious sweetheart, he's head over heels for you, babe!" Frisk froze and stiffened. 

"W-wait...You mean this whole freaking time....I'M A MORON!" Frisk said, flushing and slapping her face with both hands. 

"Yes. Yes you are. Now, darling let's get you DAZZLING! We need to impress that boy of yours!" Frisk blushed even more if it was possible. 

"Are you sure Ralph...??" She asked, shily. Ralph smiled warmly at her and the tiger patted her head. 

"Calm down, little bean. The worst thing is you two will stay friends. Ok? Trust me. I will be there every step of the way. Heck- You can even sleep at my dorm for a week if you don't wanna see him after!" Frisk smiled and hugged the tiger. 

"You're the best, Ralph." He snorted. 

"No duhh. Now...Let's go to THAT store. The cashier is cute and i need to know if he can swing my way!" Frisk smacked him. 

"YOU HAVE A BOYFRIEND IDIOT!" Ralph gasped. 

"I do! Woahhhh~" He said, wiggling his hand. They both joined arms and started laughing. 

Frisk and Sans kept spending time together for the past few weeks...She went to Sans practice, he waited of her after her courses. They spent a lot of time together. And tonight was the night. Sans and Papyrus were waiting at the door for her. 

"FRISK! COME ON, WE DON'T WANT TO BE LATE!" Frisk laughed from her room. 

"GIVE ME ONE SECOND, PAPY! I NEED TO CURL ONE LAST STRAND OF HAIR!" Sans frowned. 

"curl?" He mumbled, confused. 

"I DON'T KNOW?" Papyrus responded to his brother. The two stared at each other for a second with confusion on their faces. 

"I'm ready!" Sans turned towards her and he felt his soul thump against his ribcage in his chest. Just- woah....The dress was up to her knees, it flowed like waves and it left her shoulders bare. Her hair was curled just like she said and she was wearing a bit of make-up. She had small wings out for effect and her eyes were a light blue similar to her dress. Sans stared and could feel all the heat in his body going to his face. 

"FRISK! YOU LOOK--" 

"astonishing..." Sans finished. The two stared at each other and Frisk blushed as well, giving him a warm smile. 

"Thank you! You're very handsome as well. You too Papy!" She said, kindly. Sans was pretty sure his legs just melted. 

"thanks--" The door flew open. In walked Chara, Asriel and in front of them, Ralph. His tux had been arranged to have a lace skirt and lace accents just so he could be a little extra. Frisk gasped. 

"IT'S PERFECT! LOOK AT YOUUUU!" She said, hurrying to her friends side. Sans looked unimpressed. Chara's eyes widened as she spotted Frisk and both Asriel and her leaned towards Sans. 

"Is that really Frisk?!" Asriel asked in pleasant surprise. Sans nodded. Chara snorted. 

"You caught yourself a big fish. Damn--" Asriel smacked her over the head. 

"WELL THEN. I BELIEVE WE ALL SHOULD START GOING TOWARDS THAT DANCE IF WE WANT TO CATCH IT!" Sans scoffed. 

"leave that on me~"
