Can I Stay? (Underswap!Sans × Reader)

[Prolong]
My name is (Y/N).
I have experienced many resets, so many I have lost count. The only people who remember are Sans, Flowey, and me.
The monsters down here are misunderstood, they are afraid.
They kill me again and again.
Even Sans kills me, actually he is the most ruthless. The only one who never did was Flowey. He is my best friend, we have been through so much together.
He has taught me to fight, I never did though. I couldn't bring myself to, if I did I would be just like the other monsters.
The most current timeline, I finally convinced all the monsters that they didn't need to kill or hurt each other.
It was so hard. Sans was the hardest of them all, he...he was scared of moving forward, because he believed time would just turn back. So, what's the point?
But! I had finally broken the barrier. I- no, We! We were happy!!
...but still time reset.
Why?!?!
...
But this reset was different.
I wasn't in Underfell anymore.
