Edgy Love (fell Sans x reader)

Void Remnants

You glanced back up at the screen and watched the numbers on the heart side. You're heart rate was resting at 66 and that's all you really knew or cared about from there so then you went to look at the soul scan, or the more concerning side of things. The soul pressure and determination were all you kinda understood from Sans, as far as the resonating goes you wanted to wait for Alphys to explain. The pressure scale increased from 249 newtons to 257 newtons. Your determination level was currently at 90.832... whatever that meant. Although, Sans said it appeared to be going down less than a percent per hour so it kinda made sense.

Silence filled the room as Sans took a seat next to you yet again. Sans had his elbows on his knees as he hunched over in thought while he watched the screen. One of his knees bounced with anxiety on the situation. You wanted to reach out to sans, but you felt weak and tired and you didn't know why.

You're breathing was light, you thought about going to sleep, but you didn't want to leave Sans in the dark. "...Heya, Sansy pansy..." you mumbled to him tiredly as your eyes began to flutter open and shut.

Your light voice seemed to knock sans out of his trance as he hummed in response. "hm? what's up, sweetheart?" He asked as he gave you his attention.

"Hey... I'm feeling... weak and tired, you mind if I sleep a little bit? You can wake me up whenever," you asked him as your eyes would continue to shut for a few moments until they'd reopen. You then felt Sans rub your arm comfortingly.

"sure thing sweetheart. i'll wake you up if anything gets significantly worse, or when alphys gets back, alright? just rest easy... ok?" He said softly making you smile slightly.

"Alright... I'll try... *yawn* goodnight, Sansy," you said as you closed your eyes for the last time before falling asleep.

When you opened your eyes you were back in the familiar black stillness. "Ugh... fuck... I'm in no mood for you and your shit dude." You grumbled to the darkness that was the void. You heard the familiar rumble of the environment signifying that he was coming. You could then hear a deep chuckling sound that you did not appreciate at all... it sounded grim, dark.

"Welcome back, (Y/n), you seem to be having some problems," He said snarkily as he appeared in front of you.

"What the hell is your deal?!" You exclaimed to him. "I know damn well that you have something to do with the business of my soul, so what is your game?!" You shouted at him with pure rage.

"Heh, well that will just have to play out as it shall. Unfortunately for you, you won't get the privilege of knowing until it is too late," He said making you grow far more concerned with your situation.

"...What are you talking about?" You asked as you lowered your voice. "Why did you send me here in the first place? You must've known Frisk wasn't in any real danger, so why bring me here and lie about it?"

"Well you see, child, I have been stuck here in the void for quite some time. I missed being able to interact with people, and the loneliness and grimness of my constant surroundings for years... it really gets to one's mind. I saw you, a being with a pure determined soul. I theorized that you would be able to survive the travel of different dimensional planes without damaging your soul, with the proper practices of course." He explained making you feel guilty for being mad at him but at the same time finding his statement hard to believe because he had only been telling you lies.
