~Little Ketchup~

It was 10 pm in the underground and everyone was asleep- well, almost. A human girl was wandering around Snowdin, desperate to find the inn. Being under 0 degrees, you could understand why she was shivering,especially because she was wearing a dress. She might have passed the inn multiple times, but it was pitch black. Taking a couple of steps forward, the human girl saw the light of the bar owned by the man made of fire known as Grillby. A smile spread across her face but soon she began to feel light headed, collapsing into the cold snow.

. . .

A short skeleton walked out of the bar and saw her, a slight panic flooded through him. Was she dead? He didn't know, so he just picked her up and ran.
"Ohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygoshohmygosh! IS SHE DEAD?! Runrunrunrun!"
It was when he was outside of his house when he realised he had shortcuts.
"son of a-" Sans was interrupted by his brother.
"SANS WHY ARE YOU UP SO – WHAT'S WRONG WITH THE HUMAN?!"
"HOLY- hehe you scared me paps"
"SANS!"
"ok! gotta run! girlfri- i mean girl human fleshy person is in danger!"

Running through the door of the house, Sans cursed under his breath. He ran up the stairs and kicked his bedroom door open ,still carrying the girl. After placing her gently on his bed, Sans ran grabbed his phone and called someone for help.
"Why hello San-"
"TORI I NEED PIE!"
". . . Okay, but why at this time?"
"QUICKLY ,AND HOW DO YOU HEAL SICK HUMANS?!"
"If you are regarding to the cold in Snowdin, you'll need blankets, lots of blankets"
"OK THANKS TORI BYE!"
"Wait Sa-"

Throwing his phone at the wall, Sans ran out of his room to find anything to warm the human up. Coats, quilts, covers, blankets, jumpers, everything! He dropped them on her and hugged the pile of warmth, that she was under.
"pleasebealivepleasebealivepleasebealivepleasebealive" Sans blurted out, only to receive a twitch from the girl. After pulling away from the hug, the skeleton slumped back on the wall ,relief flooding through him.
"oh thank asgore my little ketchup's ok" Sans sighed, getting up to kiss her forehead and sitting at the end of the bed, falling asleep shorty after.

"Muh- Snans" The girl said in her sleep.
"Wa- wut" Sans wiped the drool from his mouth, curiosity forming as he got up off the floor and looked at her sleeping form.
"Mah Snans" The girl spoke again, hugging her pillow.
"daaaawwwwwww, sweet cheeks is dreaming about me"
Blushing ,the skeleton looked away, muttering under his breath.
"well she's not the only one dreaming about someone..."
His skull became a radiant blue when he thought back to those dreams. (Y/N)'s dreams seemed to be sweet dreams, like hugging and having picnics with sans. Innocent things like that, but Sans' were... different.

You could argue that in his dreams, he was hugging her, but that was a special kind of hug. Not child-friendly or even (Y/N)-friendly for that matter, but he still continued to dream them. This was one of the reasons he asked Toriel to get her dressed. Let's just say that he would... lose control.
(AHHH YOU WISH. HES A SKELETON! ALL HE WOULD DO IS GET AN X-RAY PICTURE OF YOU AND HUG IT. HIS DREAMS ARE LITERALLY JUST YOU BECOMING A SKELETON AND YOU HUG SANS' FROM THE BACK ALL THE TIME! HEHEHEHE TROLLED)

The next thing Sans knew, he was captured by the fierce (Y/N) in a headlock or a head hug. Either way, he couldn't escape. Sure, he could have moved her with magic, or teleported away, but she was in a "fragile state" as for what he thought and... he was too 'tired' to move. He's a lazy bones. Sans was basically kneeling on the floor, next to and facing the bed, with a human keeping a tight hold onto his head. She wasn't going to let go, and he really couldn't be bothered trying to escaped tibia brutally honest. He couldn't afford to care anymore.

The girl woke up after 11 hours of sleep. There she found herself holding an extremely hot skull, illuminating a light sapphire colour in the dark room.
"Oh, Sans..." she gazed down upon the glowing skeleton.
"You stayed with me..." she said, planting a kiss on his skull. With this sudden action, the light sapphire emerged into a deep cerulean.
It was (Y/N)'s turn. Her face flushed with colour and she realised he wasn't asleep at all.
"**** did she notice?!" Sans whispered to himself.
The girl picked up his skull by his hood and pouted, angry yet flustered.
"**** she did!" The skeleton once again whispered to himself, angry.
"You were awake!" (Y/N) whisper shouted.
"and you love me! dawwwww that's adorable." Sans teased.
"Y-Yeah" She shyly answered.
"dawww i love ya too, ketchup!" He replied, hugging her, definitely not sniffing her hair.
"Why are you calling me ketchup, Mr Bones?" The girl asked.
"because, sweet cheeks, you both have three things in common"
"And they are...?"
"you're both red"
(Y/N) puffed her cheeks at this comment, trying to look angry, but she just looked adorable.

"you're both things i can't live without and i'd be insane without you"

The girl's eyes softened at this.
"I love you." She whispered, snuggling into his rib cage, as he was now on the bed next to her. He wrapped his arms around her, protectively ,and pressed his teeth in her forehead.

"and i love you too, ketchup"
