Killer Sans X Reader

I ran through the marshes of Waterfalls hiding within the darkness of the caverns. Adrenaline coursed through my veins as i looked around each and every corner carefully. I didnt want to get caught, i was deathly aftaid if getting caught.

I continued on my way catiously not looking at the piles of dust that crossed my path....there was so much. I let out a breath I was holding as I finally made it to Hotland, there were still a few monsters around, but they were hiding and cowering in fear, it would be a matter of time until they found them....found me.

I paused as I saw a pile of dust surrounded by armor. I looked away, they had killed Undyne. I left the scene

I thought back to how this all happened everything was perfectly normal before this ...or at least i thought it was.

I had noticed sans was acting strange lately but he always pretended everything was okay....he tried to play it off. He looked so much sadder and depressed, like everything was hopeless. I wasnt the only one who noticed, papyrus did also....

'Papyrus...' tears prickled my eyes at the thought if him and i shook them away.

We tried talking to Sans about it, but he never opened up only said " we wouldnt understand, that its okay". We decided to leave him be, we hoped he would come to us eventually...but then one day...he changed for good.

Why hadnt I noticed it? Why didnt I try harder?...if i did this wouldnt be happening, Papyrus would still be alive.

Why couldnt I do something?

Sans and Frisk...no she calls herself Chara, they started going around killing people together for fun.

How could they!?

I cant even looks sans in the face anymore, he changed into a demon like her. He so scary and Chara. Papyrus tried to change them but that didnt happen...after I saw what they did to him I ran away in fear of my life. I should of stopped Papyrus...but couldnt, I didnt.

I arrived at Alphys lab and i entered wiping the tears off of my face. It was dark inside. I searched for the light switch finally finding it and flicking it on. Everything was okay so that means they hadnt gotten to her, i was relieved.

"A..alphys!" I called out to her but recieved no answer.

She must of left to wherever they evacuate the monsters. I dont know where that would be so this is why im still here.

I passed theough Alphys lab continuing on my way. Everything was so quiet...devoid of life. I am only filled regret for what has happened and self hate.

Chara took sans away from me and made him into what he is. Her hatred, determination, and evilness was nore than what my love could do for sans. I loved sans and i still do, regardless of what he become.

I never told him my feelings but even though did he ever love me? I dont think so.

I was now at MTT resort. I enetered the hotel and the sudden richoxhet of screams startled me. I quickly jumped behind a counter i knew burgerpants would be and hid. I fely my hands touch something and it was dust,his dust. How did they even get to him? I felt sick to my stomach, i tried getting the dust off but it was proving to be hard.

I stayed ailent as i heard foitsteps the sound of running. I peaked over the corner to see a monster I knew well it was one of the flame girl(idk her name so im just gonna gave her one)

"Saiko" i whispered yell and she turned head the look of panic and fear on her face. I beckoned her to come towards me and sge began running  for me but suddenly stopped as a knife tipped through her.
