Just this once she differs by letting them stay alife, freeing them by breaking down the barrier. What's her game? Unable to convince his friends of her true colors, he withdraws himself from them, trying to catch his breath before the next reset. But fate has its own plans and wil keep him on his toes... ~mostly Gsans pov~ (apart from a later introduced second main character) If you ever wondered how humans managed to trap the monsters down the underground in the first place, this book might be for you ;) Please dear reader have mercy, it my first time ^/////^ By the way, this will be slowburn ?...but maybe life will give us some lemons....

    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.
