You, Sans, and Papyrus were all watching a movie. Papyrus left and went upstairs, because he was tired. But you and Sans stayed. The movie had zombies in it, and Sans seemed to like it.
You'd never liked these kind of movies, because they usually ended with happiness and rainbows, but this one just met problem after problem. You dozed off after awhile.

"Getting tired?" He whispered.

"Bone tired." You said without opening your eyes.

"You stole my punch line."

"Queen of puns."

"I'm always a sucker pun makers." He winked at you when you looked over.

"Are you... hitting on me?" You blushed.

He shrugged and stood. "Maybe just..." He put his hand above his head, measuring his hight. "A little."

You blushed harder.

He made guns from his fingers and pretended to shoot you. "If you ever get bonely..." He winked. "You know where to find me." Then walked out.

You stared after him. Never, ever, had a guy flirted so obviously with you. You bit your lip. Was he being serious? You scratched the back of your head. Maybe not... no. Not a good idea. Stay down here.

You jerked up, in a cold sweat. Another nightmare. You slipped off the couch and padded upstairs. You didn't care if he was serious. You were.
You gently try the door, and it opens. Maybe he was serious. You step in and close the door softly behind you. Your eyes adjust to the darkness slowly, and you see him.
He's facing the wall, no sheets on his bed, and curled around a bunched up blanket. His breathing is even. You sneak over to the bed and hesitate. This was a bad idea. Even so...
You crawl onto the bed. It's actually really soft. You pause when he shifts lightly, but he doesn't wake up. You notice he's not wearing his jacket and look around, finding it under his head. He doesn't seem to have any pillows.
You slowly lay down on your back, staring at the ceiling. You finally look at him and scoot closer, then roll over and curl around him, fitting perfectly. He sighs shifts again. You frown.
Why is he so warm? Isn't he a skeleton? You sighed and closed your eyes.

"(Y/N)?"

You grumbled and pressed your face against the pillow.

"HUMAN. WAKE UP."

You opened your eyes and stretched. You sat up and rubbed your neck, then got off the couch.

"Wha? Wha time izzit?" You rubbed your eyes.

"LATE. WHAT ARE YOU DOING WITH SANS' JACKET?"

At the mention of his name you did a double take. The couch? Hadn't you been in his room? You reached down and scooped his jacket off the couch, then slipped it on. "Where is he?"

"OUTSIDE. HE'S BEEN SITTING OUT THERE SINCE HE WOKE UP. HE WON'T TALK MUCH. HE WANTED TO KNOW WHEN YOU WERE AWAKE."

You smiled at him. "Thank you, Pap. I'll be right back."

You pushed past him and outside. There he was. Sans wasn't wearing his jacket, again, just a white shirt, black shorts with bone designs, and pink slippers. Tacky at its finest. You liked it.

"Here." You draped his jacket over his shoulder and sat next to him. He jumped and looked at you.

"Thanks. I.... I worry." He slipped his arms into the sleeves.

"About...?"

"The human. Er, the other one. I'd like to talk to you about them."

Crap.
