4minute's Hyuna made quite the performance mistake while participating in ex-F.T. Island member�Oh Won Bin's comeback stage. Won Bin's "I Love You and I Love You" was broadcast live on MBC's "Show! Music Core", and the performance was off to a good start until Hyuna forgot the lyrics around the 2:07 mark. After the performance, a representative from Hyuna's agency spoke with Star News and stated, "Hyuna rehearsed a lot before going up on stage but ended up making a mistake by forgetting the lyrics. She had a lot of schedules to go through before the performance and was unfortunately unable to show off everything she had practiced on stage. She is extremely sorry to Oh Won Bin."
