On the wedding night, I lifted up the red hijab and saw a soaked woman lying on the groom's chest. She grinned at me, her teeth falling out one by one. I shrank back in fear, and the man grabbed me - don't be afraid, that's my ex-wife. He spoke calmly, as if the ghost was just a mosquito on the wall. Later I learned that this marriage was a deal. He helped me survive, and I helped guard his grave. But none of us expected that for every death in this city, there would be one more ghost. And the more things I touch, the closer I get to a secret - in three months, everyone in the city will be dead.
