The secrets behind Kim Jae Won's birth is inciting curiosity from the viewers.

On the Saturday episode of MBC's "May Queen," Kang San (Kim Jae Won) had a conflict with his grandfather Kang Dae Pyung (Go In Bum) about his parents.

His grandfather realized that Kang San was looking for the truth behind his father's Japanese name and says, "When did you find out? Why are you trying to find someone who's dead? Didn't I say I don't want to see his face?"

Kang San says, "They are parents to me. I have a right to know, why are you trying to stop me? I want to know my mother's name, where she was born, who her relatives her and how she met my father and how she passed away."

His grandfather says, "She made him desert everything, including his own father and son. If your father was alive, the company wouldn't have fallen apart that way, so don't talk about them in front of me."

Kang San retorts, "Fine, then let me ask you one thing. Where did they die?" His grandfather replies, "They were in a car accident in Japan and fell into the water. They got what they deserved. I raised you, don't talk about them."
