A corporate tycoon is conspired against by his trusted aide and archrival, loses everything, and plunges to his death in despair. A down-and-out office worker is reborn with thirty years of intact memories and starts from scratch.
He has never wanted to rise to the top again. What he wants is for everyone who betrayed him in his past life to kneel at his feet and watch everything he built with his own hands be [corroded] into ashes, bit by bit.
