Every day when he wakes up, Lin Xuanyi forgets who he is.
His world seems to be the same as the earth, but there are incomprehensible weirdness hidden everywhere. The only survival guide is the warning left by "yesterday's self" on the phone: be wary of the woman in red, avoid certain elevators, don't respond to knocks on the door... And look in the mirror every day to confirm that you are still yourself.
Until that day, he saw the last warning: "You are becoming the thing we fear most."
The reflection in the mirror showed him an inhuman and ferocious smile.
In order to find the truth and his lost self, Lin Xuanyi was forced to break the rules and step into the crisis-ridden outside world. He meets "awake people" who are also struggling to survive, discovers clues to the key figure "Zero", and finds a mysterious key that can open the "observation tower".
However, every time we get closer to the truth, there is also the risk of the memory being forcibly "formatted". In countless cycles and forgetfulness, he gradually touched the core of the horror: the world he lived in, called "Eden", was actually a huge virtual cage. The real world is already in ruins, and the last fire of mankind is huddled in a desperate shelter called "The Ark".
Breaking the cycle means facing a reality that is more cruel than a virtual nightmare; if you stay where you are, you will lose yourself in the remakes again and again and become part of the system.
