On the June 30th broadcast of 'Cultwo Show', Jang Do Yeon featured as a guest, and the DJs asked questions about her relationship with Seo Jang Hoon after seeing their possible love connection on 'Knowing Brothers'. Jang Do Yeon said, "It made me think that I should be more careful about what I say."
She continued, "Seo Jang Hoon is good to me in a comfortable way. He's good about it when I joke too. That's why I was playing around. I don't like tall people just because they're tall. Tall women will probably agree with me. If anything, I don't really pay attention to height."
