Mark the sassy butt as Chara and Jack the cinnamon bun as Frisk. I know this doesn't go by the story per say but you know whatever.
Mark's pov:
"What did you just throw at me spaghetti face"? I wiped off the streaks of snow that stuck to my forehead."It's a snowball! It's snow but in ball form"! Papyrus smiled all giddy.
Another one flung at the back of my head but much harder. Behind was Sans and Frisk trying to conceal their giggles.
I violently made a snowball and threw it right in Frisk's left eye causing him to stumble back.
Sans eye turned turquoise blue and more snowballs were pelted at me.
"SANS YOU-"! I growled not finishing my sentence and flung snowballs at Sans. All of them almost struck my target until he snapped his fimgers and they flunged at me.
Sean's pov:
"You took quite the hit kid". Sans laughed."Yeah thanks for the support". I pouted.
"Hey Sans keep Chara distracted. I'll go back inside. Lead him inside when I say so". And I ran off.
"Why has the human gone back inside"?
"Don't worry about it they're just making sure everything's ready remember what's today Pap"?
"Oh yes Sans! The tradition humans have every year"!
"Sans! Pap! Were ready for Chara"! I ran out and notified Sans and Papyrus.
Mark's pov:
"What are those morans going on about". I placed my hands on my hips and smiled. I could take the chance to kill-My thoughts were interrupted by a snowball slapping against my skin.
I was enraged. Sans ran off. I chased Sans and he and Papyrus made it inside the ruins before I could. They were no where in sight. It was completely quiet.
As I reached the staircase there wasn't anyone in sight. As I stepped in the kitchen there was a butterscotch pie freshly baked with a note.
Behind you!
"Wait, behind-"?
"SURPRISE"! I was tackled to the ground by Frisk. He wrapped his legs around my waist hugging me. I felt all the oxygen in me forced out.
We fell to the floor. I flipped over and he sat smiling on my stomach. There was a weird yet good feeling in my stomach as he stared at me.
"It's your birthday! Well, we don't know your real birthday so we did it on the day you fell. I guess when you fell you forgot a few thing's". Frisk bounced on my stomach.
"Get off me". It tried to maintain myself from my voice cracking as I stared at his lips.
"Happy human tradition"! Papyrus yelled out.
"Happy birthday. Brat". Sans smile widen even more when Chara glared at him.
"Happy birthday Chara my child"! Toriel was holding a cake.
"You guy's don't have to do this you know".
"Happy birthday punk"! Undyne came out and smiled a toothy grin. Alphy's was right behund her.
"Why are you all being so nice to me"?
"Because your family Chara"! I hugged Chara and he shoved me away.Time skip~
Mark's pov:
"Why are we here"? I grunted."It's a nice view of the castle and I wanted to give this to you where it wasn't crazy. And I wanted to make this moment special". Frisk happiness makes me want to smile a friendly smile but I don't give in so easily.
