She took to the girls' fancafe, writing, 

Hello, this is Youkyung, hehe.

It feels like I've come to write for the first time in a while. I feel like the reason why I'm back might disappoint a lot of people, so my heart feels a little heavy writing this. 

I'm sure there are some who have already heard, but after a lot of conversation and considerations, I have decided to end my contract with FNC, who I've been with for the past 5 years.

I haven't really had many promotions with them, and this post is not a final goodbye, but I do feel sad about the AOA members, who I've been together with since my late teens to now, when I'm 24, and also thinking about greeting and cheering the people who have always helped us. But I also feel grateful.

It was a precious time that I was able to meet great people, and also fans who have always shown love. From now on, as I always have, I'll be preparing to appear out of nowhere with a bette rimage, hehe.

Also, if AOA Black comes back with a new song, I'll unchangingly be their drummer! I'll work hard to come back as fast as I can, with the best image. Please continue to support AOA, FNC, and me! Thank you!
