The issue regarding IU's late arrival at the 'Dream High' concert has blown out of proportion however, IU personally released a apology earlier today. On February 25th, IU updated her me2day saying,

"Hello this is IU. I would like to apologize in a different manner but this is the only way for me to express my feelings so I'm sorry for posting this..�I sincerely apologize to all the people who have been hurt or displeased because�of me yesterday and today. I was thoughtless... The 'Dream High' concert was delayed because I was late. I'm very sorry to the audience, the cast, and all the people that were there. Also, I'm sorry for being immature and causing anxiety by posting words regarding a personal issue before apologizing. I was very flippant.. After being punished and regreting my actions, I will not make a mistake again. I will be a mature and adult-like IU. Those who have been disappointed because of me.. I promise you. Once again, I bow my head before many and apologize. I'm sorry."
