Lumin revealed that it blows his mind when he hears his friends saying things like, "I talk to my father about my troubles," or "I went on a trip with my father." He added that he has never done anything with his father.

When the surprised MCs questioned Sul Woon Do about it, he responded, "I don't do as much as others, but isn't it enough to just say, 'Are you doing well,' or 'Did you eat?'," shocking the MCs as well. 

Lumin then said that he had gone to the bath house once and that was for a shooting. He said, "I've never seen my father's body." And added, "I bet that he doesn't know my birthday or my phone number." 

When the MCs asked Sul Woon Do if he knew his son's birthday, the legendary trot singer hesitantly said, "February 3rd." It was then revealed that Lumin's birthday is actually on April 30. 

When Lumin had gotten his father's birthdate right, Sul Woon Do apologized and said, "I'm so sorry, but to be honest, I don't remember any of my kid's birthdays. There is no philosophy behind it, I just have no idea."
