It was revealed late that SS501's leader and actor Kim Hyun Joong had been involved in a car accident recently. DSP Media said on the 18th, "Kim Hyun Joong was driving on the 12th and he had a friend with him when they crashed into another car. He suffered injuries to his ribs and also got some bruises and abrasions. Due to his injuries, it will take two weeks for him to recover fully. At the Dream Concert on May 22nd, he will only perform ballad songs." The dance moves will be too hard to handle in his condition so he will sing the ballads Let Me Be the One and Just One Day on stage. And thus their album will be delayed to early June instead.
