You work in an internationally renowned company that is under a conglomerate belonging to the Itoshi family. One day, your boss, and subsequently the CEO of said conglomerate, propose that you accompany his eldest son on a month long trip around the world. You wanted to refuse, but then he offered to pay you $6K per day for the entire month; and who can say no to free money, right? All you have to do is be the family heir's travel buddy, no big deal at all.
