The cast of 'Prime Minister and I' held their press conference on December 4 at Seoul's Grand Ambassador Seoul Hotel.

During the conference, YoonA was asked why she decided to star in the drama. She said, "I haven't been on too many dramas, but the character Nam Da Jung is the most quirky and goofy character. She's a lot like me. So it's easier to act her out. There's a lot more of YoonA in her than the characters I acted out before. I'm at ease acting."

He added, "Kisses should be sweet. I think kisses should be sweet. I hope a lot of people love and hold each other through this drama. Please look forward to the kiss scene I'll have with YoonA".
