Sunhwa wrote on her Instagram, "To SECRETTIME fans that I am always thankful for, and to the many who supported and comforted me.. Hello, it's Sunhwa. I am writing to you today more carefully than other times. I was happy and thankful that I was able to get so much love and interest that I cannot put into words as a SECRET member for the past seven years. I am grateful that we were able to cry and laugh together. If I look back to the past days, I received love and interest for amazing things that I did together [with the SECRET members] that I could not do by myself since I knew nothing. I am sad and disappointed after making a difficult decision as well... But I want to keep those memories precious and use the passion that I've used so far into my future days. I am sure I will be lacking in my new endeavors, but I will work hard and become a person who can give back to your support no matter when and where. I thank the TS family, the members, and the fans who have been with me all this time."

Sunhwa, who has been with us for 7 years as a SECRET member, has concluded her activities as SECRET as she wants to walk the path of an actress. We cannot be together as singers anymore, but I will be supporting Sunhwa as we have lived and spent time together. We thank fans who have given us so much love as we promoted as 4, and we ask that you love and support SECRET's future activities as well. Thank you."
