On February 28, rumors about IU being hospitalized from overworking have been swirling around online communities and various social networking sites. Fan anxiety deepened as her scheduled appearance at Incheon Culture and Arts College's entrance ceremony on February 29 was cancelled.

A rep from IU′s agency Loen Entertainment cleared up the rumors and said, "IU has a cold. She went to go see a doctor, but was not hospitalized. It's not a big health issue like the rumor makes it to be and fans need not to worry."
