A Tree, For Us (Sans X Reader)

💙

No one's P. O. V.

As both Sans and (Y/N) looked for the last soul leaf, the last piece to let all the monster kind free. (Y/N) eagerly searched for it looking at every single leaf, not wanting to miss it by accident. "Have you found it yet, Sans?" (Y/N) Asked to his 'friend'.

"uh, i think" Sans answered as he hopped down the tree. (Y/N) followed his lead and inspected the delicate object on Sans' palm.

"Yeah! That's it!" (Y/N) happily chirped and took the leaf on her hands. "I'll better talk to the guys before doing this, I don't know how to break the barrier with them" She explained to Sans.

Sans nodded and gave her enough space to talk to the rest of the fallen kids.

Hello everyone!

(S,A,L&J) Hi!

Hi guys, is there anybody else?

(?) Hello. I'm Erick.

The newly found kid said to the rest, (Y/N) couldn't help but smile at her new partner. As they introduced each other, they weren't  aware of the ears listening to each word they said.

So... guys... how do I exactly break the barrier?

(C) Just bury the leaves next to it.

Okay then!

(S) Hey! Aren't we missing someone? The one Sans brought.

Oh yeah you're right.

(?) I'm here...

This kid sounded shoocked and confused, as their voice quivered. That didn't fable any of the kids, neither (Y/N).

Hey, don't worry you're fine. You can tell me your name later when you feel better.

"HUMAN! HAVE YOU FOUND THE LEAF YET?" Papyrus called out to (Y/N) from the crew of monsters waiting patiently for them. (Y/N) nodded and made her way towards them,with leaves' box in hand.

"So, you know how to break the barrier, punk?" Undyne asked.(Y/N) nodded excitedly and skipped towards Sans filled with joy. On her way there she couldn't help but feel the burning gaze of the monster king on the back of her skull. - Hope this thing works - She sighed nervously, and took a glance at her friends, all of them smiling brightly. They had been waiting to be free for years, maybe even decades. 

"Um... am a bit embarrased to ask this, but... where's the barrier exactly?" (Y/N) asked shifting her weight between her legs in an uneasy manner. 

"It's right throught that door and down the corridor" Asgore explained leading the way, even if it wasn't that necessary. (Y/N) nodded and followed him with all her friends right behind. 

As their footsteps echoed throught the corridor, (Y/N)'s heart was racing, she could feel as it was going to explode anytime soon. Her breathing got shallow but tried to keep calm. The air felt even a bit heavier for her, maybe all the emotions from the monster kind filled the entire underground, and she feared to throw everything to waste for them. Sans noticed how anxious she was, he quickly made his way to her side and held her hand. (Y/N) whipped her head at the sudden feeling, and saw Sans smiling at her. "hey, calm down. we know you'll do it" He whispered, giving her hand a reasuring squeeze. 

"I hope you're right..." (Y/N) muttered, and sighed again. - (A) He's right! (L) Yup, we know this will work. I really hope it does... -  Asgore turned a corner, with still everyone followimg inside.
