According to the girls' reps on October 17th, one of the original members Min-sun will be leaving the group, to be replaced by new member Jin-kyung (age 18, 165 cm, 44 kg). The agency emphasized the newcomer's toned body, singing, guitar and piano playing skills, and overall instrumental knowledge.

As for Min-sun, the agency said that the group was considering Min-sun's departure for awhile, especially so she can then focus on acting.
