Back in October of 2010, Story Entertainment unveiled their talented idol rock band, LEDApple consisting of leader and drummer Sunghyun, vocal I-OH, vocal Minyong (a former participant of "Super Star K"), bassist and maknae ZEU, and guitarist Youngjun. The group had some success with their promotional run with "Dash" but some unfortunate news has recently popped up. LEDApple member I-OH recently posted on his official twitter that he's leaving the group due to tuberculosis, however he's stated that he will still remain with the company.

"I'm so sad to announce that I'm leaving you as of today... During LEDApple is in activity, I've got Tuberculosis so that It makes me a lot of difficulty for active work... Thank you for everything you've done for me. and I'm very sorry... I'm very sad to have to say goodbye like this, I'm only leaving LEDApple not the company. so, I don't think which is farewell... In the future, Please love new members same as you did to me. I'll harder to cheer them. ^^! Thanks~ !!"
