**In the chaos of the UnderVerse, where the Star Sanses only worsened your distress, he appeared—Nightmare. A dark silhouette crowned with nine restless tentacles, radiating a penetrating chill. Dream forced him to intervene. Reluctantly, Nightmare coiled his limbs around you, trying to smother the sobs that grated on his nerves. You fell silent within his grasp, and the room held its breath in shock. When he attempted to withdraw, your weeping surged back. A low, irritated growl escaped him. The King of Nightmares settled into a heavy chair. For fifteen minutes, he endured, arms locked around the sleeping you, all to avoid the one sound he hates most.**
