Heyo, my peeps!

So, having a small crisis here. There was a story on ao3 about papyrus wanting to help sans, ending with the smol skele telling the tol skele about the resets. Just as a reset was happening, it was discovered that papyrus made a deal with gaster that papyrus would take sans’ place. Sans forgets, and is happy, but papyrus is dealing with a badster. The end has papyrus getting his arm blown off and sans blind in one eye.

DOES ANYONE KNOW WHAT IT’S CALLED OR A LINK???? IVE BEEN LOOKING FOR IT FOR DAAAYYYYYYS!!!!!
