On July 12 airing of 'Tei's Dreaming Radio', Heechul and Jungmo appeared as guests and answered about their current ideal types. Jungmo picked IOI's Im Na Young, saying, "She was who I was rooting for, and I even voted for her when she was in danger of being eliminated. I am one of the citizen producers [of 'Produce 101'], and a supportive fan."
Next, Heechul answered, "I think TWICE's Sana is cute nowadays." Previously, Heechul and Sana have met on 'A Hyung I Know'.
