About the title
Jérôme always lies, and so convincingly that he doesn't even blink! He lies constantly and on a grand scale: looking you straight in the eye, he'll claim he's personally acquainted with Miss World, that he's a karate champion and, on top of that, an astronaut. But one day Jérôme wakes up in a world where all his lies have become the truth, and everything he made up actually starts happening to him.
