I received an anonymous letter with only one line: "Causation is reversed, the game begins."
Also attached to the letter was an old photo of young Wu Jianguo and Wu Jiahui, with this bar in the background.
Out of curiosity, I decided to head to the bar to find out.
I stumbled out of the bar, but I saw a weird smile on my face in the mirror.
There's a new photo in my pocket: my future self standing in a bar, that revolver in my hand.
The last sentence: "If cause and effect are reversed, no one can escape."
