The exceptional Lee Bum Soo plays Kwon Yul, Korea's youngest prime minister. He's a righteous and honest widower who is great at his career, but drops the ball when it comes to parenting. Im Yoon Ah plays the young bumbling reporter Nam Da Jung, who is impulsive and a bit of a ditz. When they're involved in a misunderstanding that turns into a scandal, they have to fake a loving relationship to save both their reputations.
The face they have to show the public is one of happy congeniality, and they do it well, especially when they become strained and stiff from being absolutely livid inside - ah, but you'll have to watch it to see those hilarious scenes.
Dramas commonly use the first episode to set things up so you unfortunately don't get right into the relationship dynamics or start feeling a connection to the characters. Sometimes it even takes four episodes to get into the swing of things. Not so with Prime Minister & I! It hooked me right from the start as those smiling faces melted into expressions of derision.
