In September, T-ara resumed their activity as a group. In that month they released "Mirage", which was a re-issue of their "Day by Day" EP with additional songs. Two of the songs from the EP were also released as singles on the same day. These were "Sexy Love" and "Najgwa Bam (Love All)" (낮과 밤, "Day and Night"). "Sexy Love" made it to number four on the "Gaon" charts and number three on the Billboard Korea K-pop Hot 100 charts. While the new EP and song were a success, the group’s popularity suffered a drop due to the bullying rumors.
