To Hell and Back (Gaster x Reader)

The world was a gray canvas, endlessly dripping rain, mirroring the mood of the city. As Monarch Butterfly, you observed it all from beneath your black umbrella, a silent, predatory figure amidst the melancholy. The recent reports of Monster activity near Mount Ebott, a place you passed on your daily route, gnawed at you.

This was your world. And in it, you were the predator.
