Background and release.
The music video for the lead track, "Only I Didn't Know" (Korean: ; RR: ), features actress Park Bo-young as she is caught in a dramatic break-up story. Her ex-lover is played by singer-songwriter Yoon Sang, who also composed this piece as a gift for IU. The music video was released on the same day as the album.
The song itself is a departure from the pop-like sounds of her previously promoted song, "Good Day" (Korean: ; RR: ). It features a mature combination of IU's striking high notes, vocals and orchestral instrumentation.
IU made her promotional comeback with "Only I Didn't Know" in the television show "Music Bank" (KBS) on February 18, 2011, two days after the album's release.
As of 2011, the album sold over 23,500 copies in South Korea.
