One day, I received a letter from a parallel time and space, signed by myself.
The letter said that my girlfriend wanted to kill me, so I had to be careful. But my girlfriend was already dead, and it was me who went to the police station to identify her body.
The next day, I received another letter, the same as the previous one, in my own handwriting. The letter said that my girlfriend was not dead at all, she had come to kill me.
I didn't believe it at first, but that night someone knocked on the door, and through the surveillance camera I saw a familiar and beautiful face.
--The dead girlfriend is looking at the camera with a smile outside the door, with red lips, brown hair, and a flowing long skirt...
Intention: Skynet is as sparse as possible without leakage
