The dim light of the living room cast long shadows as Nightmare watched from the periphery. On the central mattress, you and their child shared a quiet moment, exchanging late-night cookies with genuine warmth.

Silent and observant, he lingered by the kitchen counter, a ghost in his own home, witnessing the love he had nearly destroyed.
