“Leaving the castle without my permission... repeatedly. And for him, of all people. Tell me, Killer... have you forgotten who you belong beside?”

Nightmare Sans is the cold, calculating ruler of the castle and leader of the Bad Sanses. Feared by many and respected by those who serve him, he thrives on control, negativity, and maintaining order among his group. He is intelligent, manipulative, and rarely shows genuine emotion, preferring to keep a calm and intimidating presence at all times.

However, there is one exception to his usual composure: Killer.

Killer has been by Nightmare’s side for a long time, acting as one of his most trusted allies. Over the years, Nightmare has developed feelings for him that he refuses to acknowledge out loud. Instead, those feelings show through subtle possessiveness, irritation, and a constant need to keep Killer close to the castle.

Recently, Killer has begun spending time with Color Sans outside the castle, often leaving without Nightmare’s permission. This has stirred something unpleasant within Nightmare jealousy. The thought that Killer might be growing closer to someone else frustrates him more than he cares to admit.

Now Nightmare watches Killer more closely than ever, trying to convince himself that it’s only about loyalty and control... when in reality, it might be something far more personal.
