It's been over a year since the Underground opened up and the monsters living under the earth swarmed to the surface in their thousands. The human and monster governments are taking their sweet time coming to any kind of agreement regarding monster rights and citizenship, but for the most part, in the less politically-active parts of the nation, life continues as it always has. In your sleepy little town, there are bills to be paid, tables to be waited, and few to no adventures to be found. So when two skeleton monsters move into the empty house near the café where you work, you welcome the changes they bring with them. You knew if you let them into your life they'd make interesting friends. What you didn't expect was that getting to know these remarkable strangers would be like coming home.

She is an Artist. He is a Bad Boy. This should be fun. ||a Gaster!Sans x Reader fanfic - EDITING|| Painter was always the one that got away. From the cops, I mean. This mysterious figure was Ebott City's top graffiti artist, famed for their large wall murals that always seem to appear overnight. Nobody would ever suspect that Painter was goody-two shoes (y/n) from the art store on the corner of Magnolia and Wick street. G was the badass of the city. Always riding his smokin' hot red motorcycle all over the place, he is known all around for knowing everyone, having connections, and one one of the most popular monsters in the city. Although there is a lot of racism against monsters, he is the one to usually break up the fights, and only gain fame for it. He knows everyone personally, except for two people. (Y/n) the artist, and Painter the rebel.
