T-ara is starting to make their comeback with four members.

On May 16, according to their agency MBK Entertainment, “T-ara’s Eunjung, Hyomin, Jiyeon, and Qri will be filming their music video in Paju (located in Gyeonggi province) tomorrow for their new song.”

The group was previously planning to return with all six members for their last comeback. However, when MBK Entertainment and members Soyeon and Boram were unable to come to a satisfactory agreement, the agency released the news that T-ara will be promoting as a four-member group.

Afterwards, Qri, Eunjung, Hyomin, and Jiyeon re-recorded their new song for their comeback in June.
