Survivors of the Apocalyptic World

In 2155, Don Juan woke up, and five years had passed. What was even more incredible was that he enrolled in a university where appearance was the standard. What he didn't know was that in the past five years, the world had already undergone earth-shaking changes. But he lives in a "Truman World" carefully compiled for him. Can he discover the truth? Can he save the world? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
