They continued, "As it's the stage announcing the official group name, Park Si Yeon expressed her desire to create an amazing performance with all 10 members together. However, we judged that any excessiveness can cause harm to future promotions and came to the final decision. We ask fans to excuse Park Si Yeon and also give support and encouragement for her recovery."

Get well soon, Park Si Yeon.
