On the June 14th broadcast of KBS 2TV's 'Entertainment Relay', Jo Jung Suk was asked to choose between his former co-stars IU and Shin Min Ah. In response to the tough question, Jo Jung Suk shared, "I was more nervous [in a good way] when I acted with Shin Min Ah compared to IU. I liked acting with both of them. Shin Min Ah is an actress with a goddess-like pose so I liked working with both of them very much."

On reporter Jisook's last attempt to get the lie detector to buzz, she asked for a yes or no in response to the statement, "I have been asked out by a celebrity." Jo Jung Suk couldn't lie and said, "I think so." When the reporter asked, "Is she my unni [older than me] or an actress?", he couldn't share the juicy details and replied, "I don't know."
