Five-membered group, Girl's Day, will now consist of four members. Member Ji-hae has announced her departure from the team.

According to Girl's Day's management, Ji-hae will not be participating in this upcoming round of promotions kickstarted with the release of their new album on October 26th, leaving the group for personal reasons. The remaining members will continue on as a four-membered team for the time being.

Ji-hae as reportedly been deliberating over this decision for quite some time. One of the cited reasons was that she wanted to focus on her studies as a dance major attending Sungkyunkwan University.

Girl's Day's fifth digital single set for release on the 26th will be titled "Don't Forget Me".
