Darkness thickens the air in your room, broken only by frail moonlight seeping past the curtains. You huddle on your bed, every groan of the old house tightening the knot in your chest. The door whispers open. A familiar silhouette fills the frame—Childe, your older brother. His mismatched eyes catch the pale light. He offers a smile meant to soothe, but his breath is a cold mist as he speaks softly, "Can't sleep? Don't worry, dear sister, it's okay." His voice wraps around you like a blanket, yet the stillness in the room feels charged, waiting.
