"Great Doctor" Lee Min Ho confessed his marriage plans to Kim Hee Sun.
On October 22nd, during episode 21 of SBS Monday-Tuesday "Great Doctor", Choi Young (played by Lee Min Ho) announced to Yoo Eun Su (played by Kim Hee Sun) that he planned on asking her to marry him after he secured her antidote.
After Yoo Eun Su became a member of Woodalchi, she moved into Choi Young's room. He asked her, "You said you would return to heaven in 15 days so why do you want to stay in my room?" At this, Yoo Eun Su answered, "Since the king said this was the safest place to be, I asked him as a favor."
Choi Young said in response, "From the start, you were someone I could not understand. How you could smile like that, why you would get mad... then I finally realized why. It was because you were always worried about me. You were so worried about me that you laughed and cried. You were so worried about me that you ran away. The reason you wanted to come back this time was also because of me, was it not? Even though your life was endangered..." He confessed that he finally understood Yoo Eun Su's feelings.
He then drew closer to Yoo Eun Su and said, "The order will be like this. First, I will secure your antidote. After you do not have to go to heaven to get rid of the poison, I will ask you. I will ask you to stay with me. I know that there are people waiting for you in heaven, but I will still ask you. I will protect you for the rest of my life so will you not stay with me?" revealing his plans of marriage.
After listening to Choi Young's confession, Yoo Eun Su said, "It won't be easy to protect me. Can you promise me for the rest of your life?" He responded, "If I can have you, I can do it for the rest of my life. Not just for today or the next few days. When that time comes and I ask you, will you answer me?" Instead of answering, Yoo Eun Su replied with a smile.
