Disaster Coded || Error Sans x Reader

There's only one rule for those capable of AU hopping: never bring a real person into the Undertale multiverse. But, like all rules, it was destined to be broken. |

- Error Sans x Female Reader
- Young Error - take places not long after he becomes Error - so he mimics his canon version more closely at the start before molding into my fanon version with experience
- This intentionally doesn't follow the exact plot of Aftertale either
- Achingly slow burn
- I abuse Y/n more than necessary (oops) and Error is toxic pre-character development. This isn't meant to portray a perfectly healthy relationship, but show that perhaps even the worst person can change
- The friendship dynamic is: bffs that insult each other for fun (while not meaning a word of it) & I include a lot of what's deemed 'filler' content b/w Y/n & Error (y'all just 'hanging out') bc there has to be a solid foundation for Error of all people to care about someone else
- Expect a heaping helping of banter 👍 (I couldn't help myself)
