'Prime Minister And I' Yoona chose farewell for Lee Bum Soo's happiness, but Lee bum Soo's love for Yoona got deeper and deeper.

On the KBS 2 TV Monday Tuesday drama "Prime Minister And I," which aired on January 28, 2014, Nam Da Jung, played by Yoona, left Kwon Yul, played by Lee Bum Soo, for his happiness with the children and his wife Park Na Young. On this day's episode, Park Na Young and Yoona met and Yoona said to her, "I do not want to leave the Prime Minister. But you have to come back to your original position. You are the children's mother. They want to see you. Woo Ri and Na Ra and Man Sae miss their mother. You have to go back to where you belong, even if it is only for the reason of your children."

Nam Da Jung knew that she would have to break up with Kwon Yul because of this, but she chose to say goodbye to Kwon Yul for the happiness of him and his children.

On the other hand, Kwon Yul kept developing his hearts for Nam Da Jung. Nam Da Jung gave Kwon Yul a watch for a present and said, "I hope your time does not stop." When Kwon Yul asked Nam Da Jung, "Why are you acting like we would never see each other again?" Nam Da Jung said, "It is just the words. Give it to me, I will put it on you."

Later on, Nam Da Jung made Kwon Yul meet Park Na Young. Nam Da Jung then went to Kwon Yul's study and left the ring on his desk. He said, "Bye, my Prime Minister," and left with her luggage.
