you had gone on a camping trip to mount ebbot, ignoring the warnings of the people in the village.

"don't go up there!"

"people who go up the mountain never come back!"

"you'll get yourself killed!"

you believed the rumors, and by chance...

...you fell into the underground.

~time skip to when you make it out of the ruins~

you stepped into the snow, the instant cold hitting you. you only had some shorts and a short sleeved t-shirt on. you wonder...what other monsters were here?

*your curiosity to find more monsters fills you with DETERMINATION

~time skip to after meeting papyrus~

~your p.o.v.~

I hid behind the rock and peeked out to watch what was going on. a second skeleton, much shorter one wearing a battle body comes into view. I cant hear the conversation. eventually the short one turns to leave when I slip on the ice near the rock.

"PAPYRUS! WHAT WAS THAT?"

"i dunno," I try to stand up but slip and wince and fall over.

"I HEARD IT AGAIN!" I shake from the cold and don't look up. my ankle hurts so much.

"stupid ice..." I whisper. I shadow looms over me.

"ITS A HUMAN! PAPY COME HERE! wait...human? are you alright?" I look up. the shorter skeleton holds out a hand. he helps me up and I try to put pressure on my foot but hiss at the pain.

"I'm alright- ow -yeah I'm fine," I say.

"NO YOU'RE NOT!" I try to protest but he picks me up and I blush.

"so who are you?" I ask.

"I AM THE MAGNIFICENT SANS!" sans, huh? "BUT YOU CAN CALL ME BLUEBERRY OR BLUE!" he's adorable! he carries me to his house and puts me on the couch.

~narrator p.o.v.~

you smile. Blue was so cute! you take off your shoes and socks, looking over your foot for visible injury. blue comes back with some bandages and puts your foot in his lap.

"WHATS YOUR NAME HUMAN?" he asks, wrapping you ankle.

"I'm y/n," you say. you talk about a lot of things, about life on the surface, things you like to do, stuff like that. after a long while of talking, you turn to the window, watching the sunset as you begin to fall asleep. Blue picks you up and smiles, carrying you to his room and putting you on his bed.

"b...blue...wha..." you try to continue talking, but fall asleep.

~several months later~

you had saved monsterkind and lived in a house with sans and papyrus. you had crush on sans as well, but were too shy to tell him. you had told papyrus, who approved, and wouldn't pressure you into telling sans.

"does he really feel the same way?"

"sure he does y/n,"

"you know what?"

"yeah kiddo?"

"i'll do it," you say, grabing you scarf. "wish me luck," you open the door and walk into the city. you wernt sure where he was, and pulled out your phone.

you: hey sans

sans: hello human!

you: meet me at muffets in 10

sans: why?

you: you'll see

you smiled and pocketed your phone, heading off. after a short walk, you made it and saw sans waiting for you.the

"hi sans!" you say.

"HELLO HUMAN!" he says, hugging you. "WHY DID YOU WANT TO MEET HERE?"

"um..." now time for the hard part. "sans...I-i...I love you," there. you said it.

"i like you too, y/n," he said, quieter than usual. you both blushed. then he kissed you. you didn't expect this at all, blushing harder than ever.

"s-sans?" you smile. "lets go home," he picks you up and takes you home, putting you on the couch.

"I WILL MAKE SOME TACOS!" he says, running off. you smile and spot papyrus, smoking again.

"PAPYRUS STOP SMOKING IN THE HOUSE!" you and blue scream, before breaking down in laughter.
