Sans' POV

I was walking towards Waterfall with my Hands on my Pockets.A Sudden Grab of my hand made me look.I saw y/n behind me,holding my hand.I Blushed then chuckled.I held their hand back and walked to waterfall with them. It Was Becoming foggy up ahead so we can't see where we're going. 

just a teleportation would do. I snapped my fingers and teleported to Gerson's Shop in waterfall.When I Looked at Y/n, My soul Skipped a beat And dropped the snowpoff.

Then I Hear my Name being called."SANS!!!" I Heard A familliar voice of Y/N.I Panicked and tried to teleport to every place.

'God She could be ANYWHERE!'

Your POV

it was becoming foggy up ahead,i cant see anything,not even Sans. But i know sans is with me because i am holding his hand.When its not foggy anymore. I see clearly now, but What i was holding is a snow poff.I gasped. 

I am alone in the underground. Sans is the only monster i know and trust.I stay determined and walked forward.maybe he is already up ahead?

I heard rushing of water and quiet echoes.i saw a station with a blue flower and a monster my age with no arms.i was frightened but then he looked innocent."U-um...Excuse me!" I Slowly walked to him. he looks at me."Yo,You sneaked out of town too? Haha! Don't Tell my parents im here though! Im only here to see Undyne!" He says as he tries to walk but then faceplants on the floor.

"A-are you alright?" I asked a bit worried. He Gets up by jumping and landing by feet. "I'm alright! im Used to it!" he Exclaimed."Anyways...What're you doing here?" He asks. 

"I-Im Looking for a Skeleton named Sans! H-Have you seen him?" He Shakes his head."Its just me here! I'll see ya later!" He gives a smile and turns around.before taking a step, he trips and lands on his face. he jumps up and lands by feet then he continued to walk.

'I Wonder Who is Undyne?'

I Thought and walked where the monster kid was headed.I Saw this shiny star laying on the ground.I tried to pick it up, but when i picked it up, my sight shined bright for ashort time only.it made me feel relief.but when i looked at the star,it was gone.

'strange..'

i continued walking and i passed into some tall bushes.I shivered after passing them,made me feel that im being watched. I turned around to see nothing but the tall bush."S-Sans?.." i call out.

I heard only Silence.I turned around again and continued walking.I Solved several puzzles on the way on sans but, i really feel like im being watched.i hear metal stomping and heavy breathing.

Before taking another step, A cold, Blue, Sharp, Spear Was Thrown infront of me, almost hitting me feet.I looked up and saw a well protected Monster.They jump down and Glared me down.I squeaked and ran away from them.

I Hear Summons of spears as i see two of them ahead of me.one spear sliced through my cheek, making a Wide bleeding cut in it.

The Pain makes you tear up and call out: "SANS!!!" You cry and continue to run but then you fell down onto the ground. 

I turned around,seeing The Monster that is trying to kill me. 

"H u m a n"

I backed away slowly.The monster Removed its Helmet as i see its red hair.It Glares at me with its fish eyes.

"Your soul,will be very useful to us, monsters." 

I heard its voice and Guessing she is a Female.She Raised her hands As I see Icy blue Spears Summoned Above her hand.I used my Hands as defense, But I doubt that it would defend me.I closed My Eyes, embracing For the Attack.

I Heard A wave of teleportation followed by an explosion."Huh?" I opened my eyes and saw Sans infront of me."S-Sans!" I called Him out As I Hug him."I Was so..S-Scared...." I sob in his Hoodie.

I felt Two Hands hug me Back."You Made Me Worried Sick about you.." He Mumbles.I Blushed but then quickly fades away by a rude sentence.

"Sans, You Traitor.WHY ARE YOU PROTECTING THAT HUMAN?!" I hear The fish lady's Voice.He Does not Answer But Then his grip on me becomes Tighter. I Feel His anger flowing everywhere in his Body.

"SANS THEY ARE JUST GONNA KILL YOU!!"

"DONT TRUST THEM!"

"WE NEED THEIR SOUL FOR THE MONSTERS TO BE FREE!"

"AND WE ONLY NEED TO KILL TH--"

She was cut off by Sans Staring At Undyne's Soul.His Smile Became Wider with the Ambience Changing.

"S A Y . . . "

"U N D Y N E . . . . D O . . . . . "

Before he started his next sentence,His eye glowed Blue.

"D o  y o u  w a n n a  h a v e  a  b a d  t i m e ?"

I got a little Scared because of his really deep And dark Voice, But I just Held Sans' Hand Close.He Holds My Hand Back."U-Ugh..." She turns Around And Left In the Shadows.The Ambience turned back to normal as Sans Teleported with me to his House.

"Sit down." He Says Pointing at the couch."I-Im Fi--" I was cut off.
"Its not a favor its a Command.Now Sit Down." He glares at me with No white pupils seen in his eyes. I Felt Scared again but Sat down.

He teleports Somewhere But then came back quickly with a Bandage."Now,Let's fix that Wound." His Hand Was reaching out for my wound but I backed away.I was still scared Until he notice that I was Scared.

"It's gonna be fine, dont be scared.Its just my Magic to Heal you up." He was Wrong. "I-I'm not scared about that...." I Mumbled.

"Then what are you afraid of?" He asks, placing down his Hand to his lap."I-I'm Afraid of you..." I Say, Looking At my Hands."Why? And When did I ever scare you?" He asks Tilting his skull.

"When you were threatening That Monster,Your eye turned blue.And also When you Glared at Me with pitch Black eyes just a moment ago.I-Im scared that you'll hurt me too...." I explain.I felt his Hand Cupped my cheek.

"Hey, Look at me." He Says as I Look at him with sad Eyes."I'm not here to hurt you... I'm here for the opposite of that." He Gives a small grin."Huh?" I Concentrated in the small sentence,

'the Opposite of that'

"I'm here to protect you, No Matter what." He pulls me in for a hug.my eyes widen but Hugged back.

After he heals my wound, He Placed the bandage over my wound."Its Still Bleeding but It will stop In a Minute or two." He Ruffles my hair.

I giggled and make my hair.just for fun,I pointed at my Bandage as he becomes confused."What is it kid?" He asks.

"You have to kiss it so it will heal faster! Heehee!!" You giggle as he chuckled and leaned closer at my cheek as he kisses my wound.

It was only a trick, but It felt Better when he pulled away.I Smiled as he smiles Back."You have to stay here for while,You're still not safe." I nodded in agreement and Sighed.

I felt tired in all that Running And I wanted a glass of water, but Sans Was ahead of me and gave me the glass of water."How did you know I wanted water?" Curiously asked.

"You sighed and you look really tired." He took the glass of water and teleported it in the sink.He took the T.V. Remote and turned on the T.V.

As we Watched T.V. I felt my Eyelids getting Heavier.I Slowly Drifted to sleep, but in the process of drifting to sleep, My head fell onto Sans' Shoulder.

I hear a silent chuckle.

"Sweet Dreams, y/n"
