A secret circulated at Jiangyu University: at midnight, make a wish while playing the mobile game Mirror Realm, and you will receive a trial from a "god."
Lin Che, a sophomore, was only curious, but got caught up in a deadly game. Win, and you get a clue; lose, and someone in the real world will be "forgotten."
As his classmates and gaming friends disappear one after another, with no one even remembering they ever existed, Lin Che discovers that the game designer, "Mirror," used the case number from his mother's disappearance eleven years ago.
Five levels, five altered memories. While the entire city believes he is insane, Lin Che sees "Mirror" in the final locked room: himself, the one who should have died eleven years ago.
