Damn, the Beginning Is the End

"The doomsday will begin in three days, host, please be prepared!" The cold mechanical voice echoed in his mind. The end is coming, human order collapses, morality is annihilated, and everything becomes objects, including humans.

This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
