When everyone's memories begin to go wrong collectively, you are the only one who is awake, and the world is trying to repair your "loophole".
Lin Mo, a 28-year-old book editor, discovered that everyone in the city, including himself, had lost part of their memory overnight. But he soon realizes that his "forgetfulness" is a disguise - he is the only one who remembers the truth. Mysterious "restorators" began to appear in the city, and they would "correct" those who showed abnormal memories. Lin Mo must walk a tightrope between disguise and exploration, and find other "awake ones."
