Nightmare Sans

Nightmare stared at the name on your wrist, his face twitching between a frown and shock. He couldn't believe it. But his name was written there, clearly, no doubt about it. And it was just his luck that you were fighting with his brother against his group, and of course it was during a battle. His expression settled into a grimace. "you're joking." Nightmare finally hissed, staring at you in disgust. He couldn't stop himself from thinking that you were pretty, though.
