Special thanks to a certain someone for this idea~

"Y/N, you okay?" You woke up to the soothing sound of Sans's voice.

You hadn't realized you fell asleep, or even were sleepy at all. But, you won't question it. "Sans?" You ask, making sure he was actually Sans.

"Yeah y/n?"

You nod slightly. Yep, that's him. "You okay Sans? I mean, from that whole fight with Tori and all, you should have a couple of bruises maybe-" That's when you realized something.

The crack in his skull...

...

...

It's... bigger... You point at his crack. "Sans oh my God, your crack got bigger!" Sans raises an eyebrow and walks over to the bathroom and looks in the mirror. A shocked look spreads across his face.

No, no, no, this can't be happening! Sans thinks, panicking. You walk over to the bathroom and notice his panicking, you try to comfort him with a hug. "Sans, don't worry! I'm sure we can glue the pieces back together!"

"Y/N, I'm sorry, but I can't..."

"What do you mean, can't?"

"Even if you glue me back together, I'll still fall apart!"

"I don't care how many times you break apart, I'll always try to pick up the pieces and put you back toge-"

"Y/N, JUST DON'T! THERE'S NO HOPE FOR ME! I'LL JUST HAVE TO ACCEPT MY FATE!"

"I WON'T ACCEPT THAT! I'LL SAVE YOU EVEN IF IT KILLS ME!" Sans looked even more shocked when you said that, but sighed and grabbed your hands. He looked in your eyes, and you looked at his.

"Y/N, listen...stop trying to give me all this false hope, I'm not worth it..."

"Sans, yes you are... because... I..."

"..."

"I...I lov-" You were interrupted by Sans pressing his teeth against your lips. Your eyes widened, shocked. But, you melted into the kiss, enjoying the warm embrace.

Sans pulled away from the kiss, and smiled, tears coming out his eyesockets.  "I love you too Y/N."
