At 42 years old, Kwon Yul (Lee Beom-soo) is South Korea's youngest prime minister ever. On top of his reputation of being an honest man of the utmost integrity, he's also a widower who raises his three children alone. But what the public doesn't know is that despite his perfect image, Yul is actually a struggling father devoid of even the most basic of parenting skills. Nam Da-jung (Im Yoona) is a journalist who resorts to writing for a trashy tabloid to support her ailing father, but when she chases Prime Minister Kwon for a lucrative exposé, she ends up scooping a whole lot more than she bargained for and the two end up in a contract marriage.
