You were walking around your Au, Underfell, grumbling when you saw a portal. You heard someone shout your name so you turned around and saw Sans and Papyrus. Both seemed mad at you, in fact, everyone did. All because of that human who replaced Frisk.... Frisk was your loving little sibling who was brutally murdered by this new human, so you attacked her.

You raced into the portal only to fall and be caught into the arms of another human, "A-Are you ok Y-Y/n?" She asked. You looked up and saw your best friend, Sophie! You smiled and hugged her tightly. She giggled shyly as you picked her up and carried her to her lover, Nightmare. You and him got along well and you were glad about it, which meant you could get closer to Cross! You had a huge crush on this chocolate loving floofy skeleton.

Nightmare saw you and smirked as you dropped Sophie into his arms, "thank you Y/n. By the way, Cross's over there." He said as he pointed at Cross, who was leaned against a doorway with his eyes closed.

You walked up to Cross and smiled, "Hey Cross!" You spoke. His eyes opened as a bright purple hue appeared on his face, "Y-Y/n it was a bad i-idea to come o-over here.." He stuttered. You tilted your head as he pointed up. You looked up as well to see a mistletoe hanging above the two of you. Your faces were both bright red as Cross used one arm to wrap around your waist and pulled you closer. He used his other hand to lift your chin up so you were looking at him.

Your blush got brighter, "C-Cross?" You stuttered. He closed his eyes and smashed his teeth onto your lips in a kiss. You blushed brighter but closed your eyes and kissed back. You could hear Sophie silently cheering in joy that her ship sailed.

Nightmare grinned as one of his tentacles lifted the two of you up and placed you out of the door frame. You and Cross pulled away and looked at him with confusion until he dragged Sophie under the mistletoe.

You could see a blush on Sophie's freckled cheeks. Nightmare kissed her as he wrapped his arms around her waist and she wrapped her arms around his neck. You laughed as did Cross at Sohpie's face when they pulled away. Her face was fully red and her mouth was agape.

This was a wonderful Christmas indeed.
