Having released her 3rd mini-album, "Real", just the other day, IU is ready to rock back onto the stage of SBS 'Inkigayo'! IU's new album was a huge hit even before its release, as it was reported that 5000 units of her special edition album had already sold out through Gmarket much earlier than her agency was anticipating. The special edition album, which IU considers as a thank you gift to her fans, includes not only the album, but also a calendar, post-its, and a photo spread. I think it's safe to say that even high class musicians have been looking forward to her official comeback, as they themselves helped actively promote her album through their Twitter accounts. For today's Inkigayo performance, she sang her title track, "Good Day."
