A/N: If the title isn't a big enough hint, this story is inspired by the Undertale animations and songs of the same name as the title of the video, more specifically the Frisk responce one. If you haven't watched/listened to them yet do they're really good. Anyway hope you enjoy this little one-shot.

Sans stood at the end of the Judgment Hall.

"Well lets try this again?" he asked Frisk stood still silent.

"Still no words huh? I don't blame you I'd be silent if I died THIS many times."

The red shine in Frisk's eyes flashed as Sans started the fight.

"Birds are singing flowers are blooming. Ok lets go."

After yet another round they made it to the half way mark

"Well buddy I don't think it'll work but if you give up, it'll make it a whole lot easier for me."

"…..Sans?" Frisk whispered as she dropped the knife.

Sans hesitated the red glow in his friends eyes was gone.

"What have I done?" Frisk asked as she fell to her knees and started crying.

"Buddy can you remember anything?" Sans asked kneeling next to her.

"I…I remember a voice a whisper, it grew louder and harder to ignore each time I fought…Oh no Sans I…I...killed…I'm so sorry." Frisk cried throwing her arms around Sans.

Sans for his part didn't know what to say so he just put his arm around her.

"We…we need to fix this."

"How?" Sans asked.

Frisk reached into her bag and took out what looked to a small card.

"You need to destroy this." Frisk said handing Sans her SAVE FILE.

"then you need to…to kill me" She said matter-of-factly.

"I…I don't know if I can now." Sans admitted.

"It's the only way." Frisk said by now the tears had stopped her voice was stable and almost empty of emotion.

"Alright" Sans said as he placed the SAVE FILE on the ground and summoned a number as Blasters to destroy the FILE.

After a few rounds of Blasters the only thing left of the SAVE FILE was a scorch mark on the ground.

"Now me." Frisk said

"Frisk…"

"NO Sans this is literally the only way to reset." Frisk said as she opened her arms.

Sans prepared an attack and saw behind his friend all of he bodies of her except the bodies were not like the person standing infront of him, they all had that red glow to their eyes and the jumpers were, not blue with two purple stripes but green with a single yellow stripe, Frisk had indeed been taken over, and when this timeline resets, he's going to make sure it can't happen again. Sans summoned a number of Bones to impale Firsk.

"a…Sans…it's…a…beau…ti…ful…day…out…side" Frisk coughed her voice getting weaker after each syllable.

After one struggled breath Frisk's eyes closed. Sans was all alone and felt a tear run down his face. Shortly after that tear hit the floor he felt himself being pulled backwards.

He was back at Snowdin….Frisk was right it worked.

"Sans…SANS!" Papyrus yelled.

"yeah…bro" sans said his voice dying down a little on the second word.

"Don't forget to keep a look out this time" Papyrus reminded him.

"I know…I know." Sans said

After Frisk leaves the Ruins.

After following Frisk, Sans took a deep breath and picked his pace up catching up with her. 'the moment of truth' Sans thought if her eyes were normal everything is fine, but if there was even a tiny hint of Red (like last time) Sans wouldn't hesitate to kill her.

"Human turn around and…ooff" Sand grunted as Frisk threw her hands around him.

"I can't hear her anymore, Toriel and everyone else they're ok all of them they're still alive." Frisk explained.

"I am so glad for that news my friend, but come on we know what to do next, behind that lamp kid!" Sans said.

Frisk gave him a smile before running into position.

And Sans knew that this timeline was going to be a good one.
