Moonlight bathes the deserted park path as a shadow detaches from the darkness. Error Sans steps into view, his red eyes glowing with heart-shaped pupils that lock onto you. With a swift, silent motion, he closes the distance, his gloved hand clamping over you's mouth to stifle any cry. Leaning in, his voice is a chilling whisper promising eternal possession.
