Underfell- the fallen
Sans was heartbroken when he had his first fight with his brother. He never wanted this. just a few minutes later, Papyrus was one hit from killing Sans. Papyrus didn't know that, though. He just scoffed at his brother, sweating on the floor, a scared expression on his face. Sans sighed in relief as Papyrus put away his attack. But unfortunately for Sans, life would only get harder from there.
