He held onto them, as if his life depended on it. Watching as they slowly exhaled, their chest slowly raising, them falling. 

It calmed him. He would lay on their chest and listen to their heart beat.

But now, as he put his head against their chest, he heard nothing. 

Watching as their corpse laid on the ground, eyes wide open. It horrified him. He gently placed his phalanges over their (e/c) eyes, shutting them. 

Asgore looked over at the skeleton, shaking his head pitifully. 

"You should not have gotten attached, Sans. That was not your job-"

"Just shut the fuck up.." Sans muttered, bringing the human closer to him. 

He shouldn't have said the shit he said. They weren't a hero. But they were trying to be. Trying to solve everyone's problems, including their own. 

He should've been there to support them. 

He should've. 

But after they said they shouldn't date, he sort of...

Snapped. 

He'd grown up in an environment where he wasn't used to this kind of love. Any love at that. His brother loved him, he knew that. But their relationship was so complicated. 

Both didn't know how to talk to the other, resulting in arguments.

When they came, he felt off. Usually humans were repulsed by monsters, the stereotype that a monster was under your child's bed, silently waiting for them to drift off, before dragging them  off by their feet. 

The stereotype that a monster would eat your children, devour them in one bite. 

It was all dramatised. 

They were confident. Sort of. They didn't tolerate his, or anyone's, bullshit. They made their stance clear. You were a good person. That has experienced bad things. 

Sans didn't know much about them like that, he never asked. 

It wasn't his place to. 

But the way they'd uncomfortably shift at the mention of someone's death never went unnoticed. 

Sans naturally assumed that someone close to you had passed. He never went any further. 

He felt bad for their loved one. They wouldn't want to see them that soon. 

And he hoped silently, that they didn't want to see their passed love one that soon either. 

Their face was cold. Almost freezing. The blood slowly draining from their face. Their hands felt rough, slightly bruised from their battle. Blood had run down their now faded lips, puddling on the floor.

This was all so fucking idiotic. 

If Sans had just.. 

If they had just..

No. Not them. Not him. Asgore. That prick. Sans eyed him, his smile becoming more tense. He hated him. For putting them through this. 

All for some petty bullshit that happened ages ago. Sans didn't know what, he didn't ask. And he never would unless he favoured having a spear in his eye socket. 

Sans wasn't that desperate to escape. He hated it, of course. Waking up to see the same old ceiling, the same old stained mattress, the same pillow that he would punch in frustration. 

Frisk should've set them free. But for some reason, you fell down. You'd never fallen down. In fact, this was the second timeline where the two of you had met. 

He hated it. He just wanted to be alone, why couldn't he just be alone? He didn't want any of this, he just wanted some peace. 

He wanted to be isolated. 

The king silently approached the barrier, with seven souls in hand. A blinding light illuminated the throne room, before a warm colour filled the room. Sans opened an eye socket, immediately filled with awe.

Outside the underground was a lot prettier than he had imagined. The sun was warm, like a blanket. It practically embraced him, making his bones glow. 

He loved it. He just wished they were there to witness it too. 

Fuck them for their beautiful personality. Fuck them. Sans sniffled, covering it up as he cleared his throat. Asgore looked at Sans. 

"Lovely, is it not?"

"Go fuck yerself."

Asgore sighed, placing a furry hand to his temple. "I did what I must-"

"Ya did what benefitted you, ya fucker. Stars - ya don't give two shits 'bout anyone." Sans growled, his words drenched with hatred. 

Asgore glared at the skeleton. "I can still kill you, skeleton. Unless you value your life, utilise this sacrifice." Asgore slowly approached the skeleton, his cloak dragging against the floor. 

Sans' body tensed. He began crawling away from him, you in his arms. Asgore aimed his spear at the skeleton, throwing it. It landed right beside him in a wall. Sans felt dizzy. Sick. 

Asgore smirked at the skeleton's expression, kneeling down in front of him. 

"Aren't you happy?" He smiled menacingly, his face inching closer to where the skeleton's ear would be. 

"You're going to be free."
