Mathias and Alexia have been dating for a number of years. Unbeknownst to Alexia, Mathias is having an affair with Juliette, who is a wedding planner. When Alexia finds Juliette's business card in Mathias' pocket, he hesitates, causing Alexia to stop and think - of course! "Juliette is a wedding planner, so that means that he must want to marry me!" Alexia immediately says "YES" and Mathias finds himself engaged and torn between his 'wife' and his 'mistress', while being forced to plan a wedding he never wanted.
