2階に行くな~消えた兄の警告~

My brother vanished two years ago. Now he texts: "DON'T GO UPSTAIRS." But his handwritten note begs: "COME SAVE ME." One is lying. I went up. Mom's face is reversed. Dad's hands are backward. I have six hours to escape. His rules are my only hope. But what if obeying them gets me killed?
