"frisk! frisk don't you dare!" you yelled at your older sister. she was only a year older than you, but was still a heck lot faster, despite your efforts.

"I'm gonna tell him!" she yells back. you continued to chase her before she slowed down outside the skelebro's house.

"frisk don't tell him!" you panted. she grinned at you.

"aww, but that wouldn't be fun!" she took off inside, you close behind.

"frisk! frisk don't! I only told you because I trusted you!"

"ok i'll keep it a secret,"

from then on, frisk kept your secret all while dropping hints, more and  more of them as the Christmas party loomed closer. you were sitting on your bed with frisk, when she brought up your crush.

"we don't need to talk about this..."

"c'mon, y/n. you need to fess up,"

"this isn't the right time,"

"when is the right time?"

"when I say so," you say. frisk smirks.

"how about this. if you fess up before or on the Christmas party, I wont tease you as much. if, however, you fess up anytime after, i'll make it worse, or..." frisk's smile widened. "...or i'll tell him myself. deal?" you froze, considering the options. if you did confess, what would happen? if not...he would find out anyway. you didn't want that to happen.

"deal,"

~time skip to before the party~

you still hadn't confessed, and frisk was constantly reminding you of the deal.

"i know, frisk. I get it. you've told me so many times, how could I forget?" you said jokingly.

"but tomorrow i'll tell him if you don't!"

"stop reminding me,"

you brushed the hair off your face and sighed. how were you going to tell him? you couldn't let frisk tell.

~several hours later, AFTER the party~

it was simple.

you still hadn't fessed, and you were trying to catch frisk.

"FRISK GET BACK HERE NOW!" your hair trailed behind you, the flowers on your head pulled against the wind. you wouldn't let frisk do this.

"but you didn't fess, so I can now fess for you!" you couldn't let her do this.

"i'll do it! just don't tell him!!" you panted.  

"alright, i'll give you one hour. go," she said. you ran into your room, shutting the door and breathed heavily.

you couldn't do it.

thoughts filled your head. what if frisk tells him before I get the chance? what if he doesn't care?

"i cant do it...I just cant..." you mumbled. you buried your face in your hands, having no clue what to do. you didn't hear the door open, but realised someone was in your room when they sat on the bed beside you. "go away frisk..." you mumbled.

"I'm not frisk," said the voice. you froze, looking up.

it was sans. you couldn't say anything.

"frisk told me..."

"she didn't...! sh-she p-p-promised she wouldn't t-tell," you shook in anger.

"hey, calm down y/n. she only said you wanted to talk," you relaxed.

"w-well..." you looked away from sans. "i have a confession,"

"yeah?"

"i..." your voice faltered as you struggled to find the words. you then looked back to sans. "i like you," there. you said it.

"wanna know something kiddo?"

"hmm?"

"i like you too," he said, and kissed you.

little did you know, a certain frisk was outside with a video camera.
