Childhood Sweethearts

Pressure mounts on Rénald, the youngest Prince of the Royal House of Monaco, to get married and start learning the machinery of power behind the throne. His family has been trying to find a suitable match for him, but without success. They've even gone as far as hiring a high-profile matchmaker to introduce him to all the eligible young ladies he can choose from. None of them interest him, and when his childhood best friend arrives to visit the palace, Rénald comes up with a crazy idea for them to marry each other. They like each other, trust each other, and find each other attractive. What could possibly go wrong? The short answer: everything.  Will the Royal House still be standing when this is all over?
