After making a mistake by forgetting the lyrics for former F.T Island member Oh Won Bin's Inkigayo stage, 4minute's HyunA shed tears of disappointment and frustration. HyunA's management company Cube Entertainment explained the situation and asked for fan's understanding as they commented, "On the day that HyunA featured for Oh Won Bin's stage and made a mistake, she felt so sorry and sad that she began to cry. Before there was a mistake too, so in order to create a perfect stage for that day, HyunA practiced the entire night. Up until the rehearsals she did well but she must have messed up because she was so nervous." This song was originally supposed to be featured by Brown Eyed Girls' Miryo, but due to personal reasons she was not able to feature on stage for Oh Won Bin that day, causing HyunA to act as a replacement. It was said that after the stage, HyunA personally apologized to Oh Won Bin, to which Oh Won Bin comforted HyunA by saying that she was only trying to help. Source: Newsen
