Ken Spencer is in a pinch! He needs money to pay his worker next month. His saving is already used. He also can't get any investments go to his company. Suddenly a shady application appeared in his phone. No one knows that it will be the one that change Ken's financial problem. Author Note : This is a system novel, mainly focused in managing business. I don't know if people will like this, but I personally always like Business/Kingdom/Dungeon Management type of novel. Also I am amateur at writing and also amateur in business, so feel free to correct me if you found mistake in the story. (If you are amateur at writing and business, why are you writing business focused story???)
