Siwon is the President and Ryeowook is the Santa.
Super Junior's Ryeowook shared a new picture with Siwon through his personal Twitter account on March 16. The photo is the one that Santa Ryeok tweeted. He wrote "Right before the concert of Super Show 4 in Thailand~~>< President Choi and Santa Ryeok ㅋㅋㅋ ~~~><" and attached the picture.
In the picture, Ryeowook is smiling brightly while wearing a red-white outfit that makes him look like a Santa while President Choi is at his back making a funny yet cute facial expression.
