Secret by SpiritWolfNura

They've been on the Surface for 5 years now. Everyone got the jobs they've always wanted. Asgore owns a flower shop, Toriel is a teacher, Alphys is a technician, Papyrus and Undyne are police officers.. Sans.. well, he's a lazy boy. Or so everyone thinks. When Sans gets arrested for illegal dealings, they're not so sure about that anymore.

Cherryberry: Why Do I Like You?! by GriffinGirlElizabeth

Underfell! Sans(Cherry) and Papyrus(Boss) had gotten in serious trouble for almost shattering a innocent monster's soul. But Undertale! Sans(Sans) has a better idea than just sending Underfell Sans to Error!Sans(Error) in his private jail. Instead, Undertale! Sans decides to send Cherry to live with Underswap! Sans(Blueberry) and Papyrus(Orange) in Underswap. Can Cherry survive Underswap without killing anyone? Or will he fail and be sent to Error's prison in Errortale? And what happens when Cherry starts to grow feelings for the adorable person that is Blueberry?

× [Sickness] × || Undertale Fanstory || The Gasters/Skeleton Family by Nanaz_Nazmaki

One day, Sans fell sick. His sickness came out of nowhere and it cannot be cured no matter how many medicines Gaster gave him. Because of the sickness, Sans stayed still on the bed, just laying down or sitting on it under the blanket. The sickness can be seen from his face, half of his white skull was a little bit darker than the rest. Gaster and Papyrus had no idea what kind of illness Sans has, but they decided to take care of him no matter what, hoping that the sickness will soon gone either because of the medicines Gaster gave him, or disappears itself. But alas, The sickness gotten worse... -------- UNDERTALE (c) Toby Fox --------- This have nothing to do with Undertale's canon characters or story. This is just a fan story I made because the idea stuck in my head for a few while and I'd like to share it with all of you. So, enjoy!
