'Radio Star' producer, Hwang Gyo Jin, said on January 7, "During the recording of 'Radio Star' back on the 6th, Hani successfully completed it with the other MCs and participants. It was her first time at a place of discussion after acknowledging her relationship [with Junsu], so she was very nervous.  That's why the production crew was also very careful. She is such a smart and polite friend, so we carefully mentioned [Junsu] in a way that would not make the atmosphere awkward.  You can confirm the exact details during the broadcast."
