Nathan Cross had hit the jackpot with the system!

A fleeting wish had come to pass in his wildest imagination!

From a man who had contemplated ending it all. Now to a man who holds the potential to overturn the current system of the world.

Nathan Cross decides to live by his own rules this time around.

...And what better place to start than teaching his conniving, cheating girlfriend a lesson she would not forget before walking his way up.
