Soyu went on, "Even if he's a lot older than I am, it's okay as long as I don't feel the age difference."

She then revealed who she chose as the person farthest from her ideal type, pointing at the other guest next to her, Jun Hyun Moo. She explained, "First of all, he talks too much. I mean, it's okay to have a lot to say, but it'd only be okay to have a lot to say if it were interesting. He says too many useless things. And he lies too much."

Soyu also told the story about when she and Jun Hyun Moo first met and he asked for her number. He then texted her later, saying he would buy her meat. �

Jun Hyun Moo defended himself, saying that he was familiar with the hard times girl groups had particularly during their rookie days. He then dissed himself, saying, "I've done that to IU before too. IU just said to me, 'I make more than you,'" causing everyone to laugh. He continued, "I was very embarrassed."
