Kim Seok-woo aka Rowoon of the K-Pop group SF9? has left the group after 7 years. Ever since he stepped into the acting industry, Rowoon had been unable to focus on group activities. After leaving the group, he wrote a handwritten letter to fans. In the the letter he wrote, Hello, this is Rowoon, I think I had a lot of trouble deciding what/which word to start with. It's been a while since I've written anything & I'm actually a little scared. I think I've become a little more used to being active, trying out new things & being stricter with myself. There was a frustration that I couldn't explain each and every misunderstanding, big or small and it was a time when I focused on what I had to do right away, thinking that one day, the sincerity would be conveyed.
In addition, he said, I understand that receiving attention & support can be heart-warming, but I guess I'm a bit soft. Sometimes, when misunderstandings arise, one needs the courage to say no, but those were the days when I was always busy hiding it. I'm truly sorry if there are any fans who felt hurt, and disappointed by my complacent attitude. If you felt familiar with me because I was different from before & would also have felt sad or disappointed because I hid myself. I sincerely apologise.
His agency FNC Entertainment has said that the group has renewed their contracts except for Rowoon. The team will be organised as an 8-member group excluding Rowoon, as he further wants to focus on acting.
