IT IS TIME.
Swapposite!Sans cares wayyyyyy more about his job than in canon. Tbh he's a lot like the original Underswap!Sans aka Blueberry Sans, but I tried to make it different, since this is just an opposite-personality AU. Toriel asked him to unalive Frisk, but he doesn't really care for promises. Or puns. Or ketchup. He's more of a mustard guy, honestly.

Ask questions in the comments! (if you want ofc)
