Lucky Day(2012)

A wedding is supposed to be the happiest moment in a couple's life. But what if someone among the attendants does not wish success for the newlywed couple? One morning, Takako, a wedding planner, finds a threatening letter sent to the wedding hall that says, "Cancel today's weddings. Otherwise, you will receive divine punishment." There are five weddings scheduled that day, but Takako ignores the letter and decides to duly host the weddings and find out who is behind the threat.
