Choi Soo Han learned that his birth mother Jung Ae Yeon who he thought was dead was alive.
On the 16th episode of KBS 2TV Monday/Tuesday "The Prime Minister and I" broadcast on February 3rd, Minister Ryu Jin Ki (played by Ryu Jin) went to Kwon Yul (played by Lee Beom Soo) to discuss the matter of Park Na Young (played by Jung Ae Yeon), the actual sibling.
Joon Ki asked Kwon Yul to take Park Na Young back but he said it's hard.
However, Kwon Woo Ri (played by Choi Soo Han) heard this conversation by coincidence. Woo Ri was shocked and Kwon Yul suggested, "I was going to tell you anyway about this. Shouldn't you have to meet Mom once?"
However, Woo Ri said, "Where is my mother? My mother died of a car accident. Does it make sense that she didn't come when she was alive? What kind of mom is that?"
More than that, she said "I don't need a mom. I won't meet him" and refused to meet him.
