Super Junior's Siwon recently visited the concert stage to support Brian and Hwanhee's concert as duo Fly to the Sky!

"Visited the Fly to the Sky concert," he posted on Twitter earlier. "Brian's mother asked me to lower my height. It was really fun. Flying hyungs, you worked hard! Awesome!"

Leaning as low as he could and holding a glow stick from the concert, he proudly showed off his fanboy status to the power ballad duo!
