Y/N has carried a small worn notebook for as long as they can remember. Whatever they write in it becomes real. No rules. No instructions. No one knows. For a while it feels like a gift. Small fixes. Quiet changes. A life slowly shaped into something easier. But the notebook is literal and the world is not and consequences have a way of landing somewhere Y/N never intended. Nova gets protected and Sera absorbs the fallout without knowing why. Jasper gets closer and Y/N gets more careful. Edith shows up and says nothing helpful on purpose. Rue exists and Y/N has to live with that. Then one night Y/N reaches for the wrong notebook. What gets written cannot be unwritten. The page stays. The consequences stay. And Y/N is left holding the one thing that can change anything in a world that now needs changing in all the ways the notebook cannot fix.
