Through Twitter, T-ara's Jiyeon apologized for her broadcast mistake during MBC's 'Music Core'. On June 25th, Jiyeon tweeted, "There was a sound mistake during Music Core, I'm really sorry." She added, "The mic turned on while I was practicing my next lines. I will be more careful next time." Meanwhile, during the broadcast of 'Music Core', Jiyeon's voice suddenly came on during FT Island's goodbye stage - causing the broadcast accident. The phrase, "You can't forget this person when talking about Hallyu..." was heard, which happened to be the MC's script to introduce the next singer, Kim Hyun Joong. However, the production crew of 'Music Core' carried on without a word of apology during the show, upsetting the viewers. Thinking ahead, Jiyeon sent her message of apology before the production crew. Netizens praised Jiyeon for apologizing, stating, "Your thought is deeper than the production crew" and "Everyone makes mistakes, but it's only right to apologize."
