Even with their twenty-year age gap, actor Lee Bum Soo and Girls Generation’s Yoona show their impressive chemistry for “Prime Minister and I”.

Still cuts reveal the young reporter and the respected prime minister in an unexpected dilemma. Yoona’s character Nam Da Jung was caught sneaking into the minister’s office by none other than Prime Minister Kwon Yool himself. Lee Bum Soo is seen covering Yoona’s mouth to help her escape from his office employees, but the unexpected closeness and skinship leaves Yoona flustered.

In another set of photos, Yoona is seen with her trademark bright smile, lighting up the whole set with her contagious energy. According to drama representatives, “Yoona is the endorphin on set and she always films with a smile that rejuvenates the tired production staff. Lee Bum Soo, Yoona, Yoon Shi Yoon and the other cast members are filming with a friendly atmosphere. Please look forward to their performance.”

“Prime Minister and I” premieres on December 9.
