Geng still in contact with other members

I was hoping for him to say Heechul T.T well, from what I've read it is Siwon and Ryeowook. I'm not surprise about Siwon lol they're so called 'sworn brothers' but Wookie ? Hehe. He respects Geng I suppose. As a leader. And oh once I read about Siwon promised a fan that he would take care of Geng. He really did lol. Typical Siwon.
