Actor Sung Dong Il, who plays Ko Ah Ra's father in "Reply 1994," confessed to Jung Woo, "You are my son," making Jung Woo break down in tears.

On the nineteenth episode of the cable channel tvN's Friday Saturday drama "Reply 1994" which aired on Saturday, December 21, 2013, Sung Dong Il, played by Sung Dong Il, visited Sseu Re Ki, played by Jung Woo, whom he had not seen much after Sseu Re Ki had broken up with his daughter, Sung Na Jung, played by Ko Ah Ra.

Sung Dong Il said to Sseu Re Ki, "Are you doing okay?" And Sseu Re Ki said, "Yes, I am doing fine," but shed tears, suggesting that he is having a hard time.

Sung Dong Il then said, "Do you know why I was opposed to you going out with my daughter? I do not know how you would think about it, but you are my son. After letting Na Jung's brother go like that, you came to us as a son. I felt anxious and sad that I am going to lose another son like this."

Jung Woo, after hearing it, broke down in tears.
