Undertale One-Shots

Sans x Ketchup

(I genuinely think that there should be a ketchup character in Undertale. Ketchup deserves some love - the good kind ;) )

It was 6pm, and Snowdin was peacefully quiet. A few monsters were strolling through the winter snow, chit-chatting as they walked. Quite a few of the monsters grew cold, and decided to go into Grillby's for some warmth.

Grillby's was filled with a decent amount of monsters, and the warmth from the place enveloped the monsters as soon as they walked in. It was a nice, calm atmosphere. Everybody was having a good time. Except for one.

Ketchup sat miserably on Grillby's bar, sighing with frustration. They haven't seen Sans all day. Papyrus forced him to go on patrol for humans, and from the looks of things, the taller skeleton seemed to not give the shorter skeleton a break.

Grillby walked up to Ketchup, and sat down next to them.
"I'm sure he'll turn up soon." Grillby mumbled. Ketchup looked down glumfully.
"I doubt it. It's not fair. I even polished myself for him!" Ketchup cried. They wasn't sure if Sans was aware of their feelings yet, and they decided that today was going to be the day where they would confess their feelings to him. It was so typical that Sans didn't show up today, of all days. Grillby patted Ketchups head lightly, and wandered off to take care of some customers.

"Of all days..." Ketchup sighed. They suddenly felt a tap of their shoulder, and turned around.
"Oh, hey Mustard." Ketchup said.
"Has he still not shown up?" Mustard asked worryingly. Ketchup shook it's head sadly.
"No, he's not. It's fine though. My feelings wouldn't matter in his eyes." Ketchup responded, trying to look positive. Mustard looked at Ketchup with sympathy.
"I think they would more than you think. Don't worry. I'm sure he will show up sooner or later." Mustard said, and went off to see Salt and Pepper.

"I wish you were here, Sans..." Ketchup sighed.
"You called?" A familiar voice spoke, and Ketchup jumped in surprise.
"Oh my gosh, Sans! Hi! Um, how was the patrol?" Ketchup asked hurriedly, hoping that Sans would forget about what they just said. Sans chuckled.
"Meh, wasn't much fun. All we did was calibrate puzzles and stuff. I could think of better things to do." He answered.
"Like what?" Ketchup asked. Sans smirked.
"That's a secret." Sans said, winking at at Ketchup. If Ketchup could get any redder than they currently were, then they would be.
"O-oh. Okay! Well, want some f-fries or s-something?" Ketchup stuttered.
"Nah, I'm not hungry. Thanks though." Sans replied, looking away.
"Hey, wanna go outside?" The skeleton asked. Ketchup nodded, and followed Sans outside into the snow.

"Brrrr, it's cold out here..." Ketchup muttered, and Sans took off his coat and gave it to Ketchup. The condiment blushed, although it wasn't very visible, which Ketchup was thankful for. The two began to walk down a snowy slope that led to the forest, before Sans stopped them. Ketchup looked at Sans quizzically.

"Um, well, I wanna talk to ya." Sans said. Ketchup nodded.
"Erm, I heard that you had feelings for me..." Sans mumbled, looking into Ketchup's eyes, with a small baby blue blush on his face. Ketchup looked at Sans in shock.
"Oh! Erm... Who told you that...?" They asked.
"Mustard." Sans replied. Ketchup vowed to punish Mustard as soon as they could.
"O-oh. Okay..." Ketchup said, looking down nervously. Sans coughed before saying, "So... Is it true?". Ketchup froze.
"..."
"Well?" Sans asked.
"..."
"Ketchup?"
"..."
"I'm sorry... I guess I went too fa-"
"Yes. It's true." Ketchup finally answered. They stared hard into the ground, their heart beating at a million beats a minute. They finally said it.
"Oh... I see..." Sans said, and Ketchup looked up. Sans' face was completely flushed a bright blue, and he was shuffling on his feet. Ketchup stared at Sans.
"Are you...blushing?" They asked hesitantly. Sans blushed harder.
"Ketchup, I've gotta tell you something." Sans said, looking lovingly at Ketchup.
"Y-yes?" Ketchup asked nervously.
"I love you. I always have. Ever since I met you, my life has changed for the better. I love you, Ketchup. Be mine forever!" Sans shouted, his blush at a maximum now.

Tears began to run down Ketchups face. They couldn't believe that this was happening!
"Oh my gosh! Yes! Of course I will Sans!" Ketchup cried, and jumped into Sans' arms. Sans kissed Ketchup passionately, and neither of them could get any happier. This was the best day of their entire lives.

Done! Don't ask why I did this. I just think that these two are the ultimate ship! #OTP ;)
