On the episode of KBS 2TV "The Prime Minister and I" broadcast on December 23rd, Da Jung (played by Yoon Ha) tried hard to find a marriage contract and made a fiasco as if like "Mission Impossible."
While Da Jung was not at her seat, Man Se (played by Lee Do Hyun) folds a lot of papers including the marriage contract in the shape of a frog. At this, Da Jung was nervous that she had lost the marriage contract and after not finding it, she felt sure that the frog that Man Se gave Joon Ki (played by Ryu Jin) was the contract and goes into Joon Gi's house secretly.
Da Jung said that she was there to look around the house and goes to Joon Gi's house. She looks in all the bed stands and underneath it and it looked as if she was acting to "Mission Impossible."
Finally, Da Jung finds a paper in the shape of a frog but at that moment, Joon Gi came into the room. Joon Gi said, "What are you doing there?" and guarded her and shooed her away saying, "I thought you came to look at the house.
Da Jung tried to take the frog-shaped paper but Joon Gi thought something was weird and took it from her. He opened it.
Meanwhile, the paper turned out not to be Joon Gi's and the real marriage contract was in Da Jung's room. Yul who found this started to hold Da Jung who didn't take care of the contract.
