Park Se Young and Ryu Deok Hwan may soon be sharing rooms. 

On the Tuesday episode of SBS "Great Doctor" Princess No Guk (Park Se Young) is worrying about King Gongmin (Ryu Deok Hwan). 

King Gongmin is himself concerned about how exactly he will go about trying to fight against Ki Chul (Yoo Oh Sung). Then, the princess comes to find him just as he steps out for a brief moment. She then tries to figure out if there is anything she can do to ease his burden.

She asks the palace servant, "What do you do when your man is under a lot of pressure and feeling down?" Servant Choi says she does not know and asks the male servant nearby. He says, "My wife brings me a table of drinks and food."

The princess asks, "Do you feel good when she does that for you?" He responds, "It's not just because of the table, it's what comes after you drink a little and..." He is unable to continue in her presence and Servant Choi tells him to continue the story.

He says, "I ... I go to bed with my wife." At this statement, the princess blushes profusely and at this moment, the king returns and she runs out in order to hide her embarrassment. The King asks the servants what happened and they are unable to tell him as well. As the princess and the King get closer and become more romantic, the issue of sleeping together has now been addressed.

The princess and the King, who are the other couple next to Choi Young (Lee Min Ho) and Yoo Eun Soo (Kim Hee Sun), are also drawing the attention of the viewers with this particular conundrum.
