JinE had taken a break from promotions because of her anorexia, and is currently undergoing treatment at a hospital.
WM Entertainment said, "We are preparing for their comeback, but the exact time has not be determined. They're going to come back during the spring season. As for JinE joining the comeback, we're going to decide after talking about it thoroughly with JinE and her parents."
Hopefully JinE recovers soon so she can join the rest of the girls.
