On October 3, Star Empire officially announced, "The contract with Hyuna, who has been with us as the member of Nine Muses for the past 6 years, has been terminated. After taking time to discuss the matter with Hyuna, we have decided to respect her desires to expand her career in other forms. Please give Hyuna, who led the team and worked her hardest as the oldest unnie of Nine Muses, your love and attention as she starts off anew."
Hyuna also through her fan cafe, "It feels unreal even though the decision was made after giving it thought for a long time. I feel like I'll always be here laughing and chatting with my members and being happy from my fans' love. I am a bit scared and also lost, but I will not forget the passion I had as the oldest unnie of Nine Muses."
The team will now continue promoting as a group of 5 with Hyemi, Kyung Li, Sojin, SungA, and Keumjo.
