You, Sans and Papyrus are having dinner at home. Spaghetti as usual, but you noticed something off about Sans today. He would always give you a wide forced smile when you'd go up to him, and when you talk to him he'd get flustered at times. He had became nervous today for some reason. At the Table he just keep his eyes planted on the spaghetti as he twirled the spaghetti onto the fork not even eating it. You and Papyrus just talked about other things without Sans, but he would crack a pun every now and then. You were still concerned and worried about him although. You were determined to find out what was up with Sans today.

You try asking him when you found him sitting on the couch in the living room, but he backed out of it switching the subject by telling a joke.

"(Y/N), why couldn't the bike stand ?"

"I don't know Sans. Why couldn't the bike stand?" You decided to play along for now.

"It was to tired!" He held up two fingers as he said this and you both laughed.

You were gonna ask again when it suddenly got quiet, but he saw that you were going to say something so he quickly asked you something before you can ask your question.

"Do you want to go for a walk?" He starts getting nervous again.

"Um sure." You say with a forced smile.

You and Sans go out the door and he holds out his hand and you take it. It was cold out, but you can handle it for now. You and Sans were now walking through snowdin holding hands, but Sans takes a turn. You see a figure wearing a purple cloak in a boat. As you get closer to the figure you try to see its face, but the cloak completely covered it making it look like an empty void. Sans let go of your hand and went up to the figure in the purple cloak. You tried to hear what he was saying, but he had been whispering. You started to become very curious. The figure started to laugh with a very high and suspicious tone, and turned towards you with Sans. You give Sans a questionable look and he shrugs.
Sans takes out his hand and you take it once more, and he leads you inside the boat. As you two take your seats the figure in the purple cloak looks ahead from the boat, and the boat begins to move foward in the river.

As the boat moved along you and Sans talked like how you usually do. You still were worried and concerned with Sans although. As the boat kept moving forward Sans would start looking flustered. It looked like we were heading to the waterfall.

You loved the Waterfall, it was your favorite place in the underground. The scenery of everything is just beautiful, and you always went there every time you were feeling down. It never got to old to still be in awe with everything. Your favorite part of it all was the echoflowers, you'd always have a laugh with them as they repeated everything you say in a lighter tone.

You were getting cold and Sans seemed to notice this. The cold breeze hit you, and you regret not bringing your sweater. You were shivering not being able to stand the cold any longer. You feel warmth around you as Sans placed his sweater on your shoulders.

"You look chilled to the bone there (Y/N)." Sans smiled at you as you zipped up the blue hoodie. It smelled like ketchup mostly, but you didn't care since it was warm.

"Thanks Sans" you laugh before responding. You thought of a joke in your head and smirked at Sans. "Hey Sans."

"Yeah (Y/N)?" He looks at you suspiciously.

"Why do skeletons hate winter?"

Sans starts to smile genuinely before he responds." I don't know, you tell me."

"Because the cold goes right through them!"

You both start laughing in the boat, and you can even hear a slight chuckle from the figure in the purple cloak.

You and Sans arrive at the waterfall, and you both lay down under the glowing stones listening to the sounds of the illuminating water cascading down into the river as it flows along calmly. You close your eyes enjoying the moment your having with Sans. You hear Sans moving and you open your eyes to see him sitting up looking at you calmly with a smile on his face. You sit up as well, and give him a soft smile in response. You see Sans looking down to his pocket as if he was holding onto something. He notices you looking, and you look up at him seeing his smile falter with a slight blue tint. He stands up liftting you up with him. He gazes into your eyes while his grin returns.

"K-knock knock." You start to question the sudden joke after what seemed to be a serious moment.

"Who's there?"

"Marry." His eyes start to widen still looking into your eyes.

"Marry who." your voice cracks as you start to feel tears building up in your eyes.

Sans gets down on one knee taking out the item from his pocket. It was a small box, and he held it up in front of you in his hands.

"Marry me." He made a small grin looking down to the box as he opened it revealing a ring with a blue diamond that shone at the light of the glowing stones above you.

You feel tears of joy rolling down your cheeks as you begin nodding speechless at his actions. You feel your face grow hot, and you cover yourself with your hands that were covered in the sleeves of Sans hoodie. He stands up, takes your hands from your face taking the ring from the box, and carefully placing it on your finger. You both start blushing madly starring into each others eyes. You pull him into a hug tackling him down to the floor. He wraps his arms around you, and tightens his grip. You lift your head up feeling his boney fingers wipe your tears. He goes back to hugging you afterwards.

"Sans, this is your best knock knock joke yet."
