"Great Doctor" Kim Hee Sun and Lee Min Ho are finally making headway in the area of physical contact.

On the Monday episode of "Great Doctor," Choi Young (Lee Min Ho) taught Yoo Eun Soo (Kim Hee Sun) how to swordfight and expressed how much he cared for her. 

Choi Young realized that Prince Duk Heung could have access to Eun Soo's notebook and said, "Find the notebook and solve the puzzle. If Duk Heung is to solve the problem, Ki Chul may not just stand by idly. 

Choi Young tells Duk Heung that Eun Soo can use a sword well and to watch out. Now worried about her, he taught her how to wield a sword. He accosted her saying, "How are you going to attack when it takes you that long to pull out the sword. This will be lighter." He hands her the smaller sword and says, "This is the most effective in the short amount of time. Try attacking me."

As the two of them continued to practice, they had inadvertent physical contact and the mood became slightly more romantic. After practice, she says, "I like it here too. The air is nice and it's quiet." He replies, "But you still want to go back? And you're just trying to adjust?"

Just as Choi Young said, Duk Heung comes to find Eun Soo with her notebook and Choi Young faces treason charges from Ki Chul.

In the preview, Eun Soo runs into Choi Young's arms, indicating a more maturing of their romantic relationship.
