[Sans POV]

I sit against the door that leads to the ruins. Not knowing what to do I just sit there waiting for someone to come. I hear footsteps and then someone sighing. A few minutes pass and then I hear Y/N's voice.

"This place is too small for my liking." she says talking to herself. 

"Then why don't you leave it then Y/N?" I say just realizing what I said. There was silence for a couple minutes but she replied

"I don't know if i can" she says sadly 

"I don't know how." She says shortly after that.

"Well for starters you leave the ruins from this door." I say trying to sound calm.

"R-Really" she says really excitedly. I smile at her voice and continue to sit there.

"Thank you so much I must be going now." she says quickly. I hear her running down the hallway and she was gone. I laugh that girl is crazy. I get up and head to grillbys. 

[Y/N POV]

I rush to pack my bag full of the clothes Toriel bought me. I also pack my journal and the only thing I had with me the night i fell down to the underground my F/C hoodie. As I finish packing Toriel walks in to my room carrying a dress.

"Y/N I got you a dress I thought you might want one to wear for some nice occasion." Toriel says looking at you and smiling. 

"Thank you Toriel." you hug her and smile.

"But I need to tell you something." you say looking sad.

"What is it my child?" Toriel looks a little worried.

"Well I think its time for me to leave. I-I mean i love your company and the ruins are just so small and-and." you trail off not knowing what to say. You look at  Toriel to see her smiling sadly.

"I understand Y/N I'm not going to stop you from leaving, and yes i know it can get a little small in the ruins"she looks at you and gives you a hug.

"Thank you for everything Toriel." You say wiping away forming tears. I wont ever forget Toriel.

You walk down the stairs for the last time to the hallway. You wave goodbye to Toriel and walk up to the door. You open the door and walked out into the open cavern. Closing the door behind you you take a few steps forward. There was trees and the cold air around you took you for a shock. You continue walking til you come across a bridge and you stop. You were about to cross it when you heard someone behind you call your name.

"Y/N???" they said in surprise. You turn around to see a skeleton staring at you. You jump away from the skeleton that some how knows your name.

"A-and you a-are." you say in a shaky voice. He looks at you and smiles

"I'm Sans. Sans the Skeleton and we have talked before remember." he says smiling while pointing at the door. You realize who it was and relaxed a little.

"Oh okay nice to meet you in actual person Sans." you smile and take a step closer to Sans. You hold out your hand for a hand shake. As you and San's hand collide together there was the sound of two whoopy cushions going off at once. You both burst out laughing.

"I can't believe we had the same prank in mind. HaHaHa" Sans starts snorting while he laughs making you laugh harder.

"I  guess great minds think alike." you say still chuckling.

"Yeh no kidding." He replies. 

Your start to walk across the bridge when Sans grabs your hand.

"Wait I need to tell you my brother is over there and hes pretty much harmless so don't worry about him." he says with a worried tone.

"Ok I wont worry about him." you reply simply. You notice that he still has your hand and you start to blush. He looks down at your hand and quickly lets go. His cheeks turning a light blue.

"Well I'm gonna get going."you say plainly and start to walk across the bridge waving bye.

[Sans POV]

She walks out of the door her h/c hair was long stretching down to the center of her back. She wore a t-shirt with skinny jeans, she also had a blue scarf around her neck. She looked around and smiled then continued to walk down the path. She stopped at the bridge and you thought that it was the perfect time to talk to her.

"Y/N???" you say in a surprising way. She turns around looks at you for a second then jump away from you. You look at her thinking shes pretty cute she was shorter than you were but not too short maybe around 5'3. She looked to be around 18 and had the most craziest look in her eyes.

"A-and you A-Are?" She says with a shaky voice. I smile a little and look in her eyes.

"I'm Sans. Sans the Skeleton and we have talked before remember." I point at the door and she relaxes a little bit. 

"Oh okay nice to meet you in actual person Sans."she replies stepping closer and holding out her hand. You knew this was the perfect time for a prank. As your hand collides with hers the sound of two whoopy cushions goes off. You burst out laughing thinking this girl is the best thing since grilbys opened up. She laughs even harder when you start snorting smiling for a while.

"I can't believe we had the same prank. HaHaHa." you tell her still snorting and laughing.

I guess great minds think alike." she replies still chuckling.

"Yeh no kidding." you reply look at her for a second.

She starts to walk across the bridge and you panic grabbing her hand stopping her in her tracks

  "Wait I need to tell you my brother is over there and hes pretty much harmless so don't worry about him."  you say worriedly. Her smile gets more happy looking

"OK I wont worry about him." she replies. She looks down at her hand and her cheeks started to turn pink. You follow her eyes to what shes looking at you noticed that your hand was still grasping her. You quickly let go before she questioned you. You felt your cheekbones blush a little.

"Well I'm gonna get going." she states as she starts walk across the bridge. She waved goodbye to you but she doesn't look back. You notice the scar on her arm and wonder where it came from but don't give it much thought.

A/N: Hope you enjoy more to come. :3
