Yoo Jae Suk simply said, "The viewers all know about it already, so what are you talking about?" Shinji even added, "It's funnier if we pretend we didn't know about it," causing laughter.

Yoo Jae Suk continued, "After 'that incident,' I had once said to Yewon, 'I'm sorry for some reason.' �I said this to her as a joke during ToToGa: 'Why do you lie?' �Honestly, at that time, I said that to try to create a character for Yewon. �But after Yewon's incident, reports came out saying that I had foreseen it. �So I do wonder if I really did foresee it," causing more laughter. Well, you didn't make it happen!

Yewon also said on the show that after the controversy, she does not lie, so she's telling the truth when she says on the show she does not have a boyfriend.
