It's Shinee, during their Ring Ding Dong promotions, some people caught the swine flu so they were using SUJU members as substitutes
"Ha...ㅠ When it comes to swine flu, the first time that comes to mind is that one of the members caught it during Ring Ding Dong's promotion and (..ㅠ) Suju sunbaenims had to substitute for them in their stage"
"Not only Leeteuk Sunbaenim ... Yesung sunbaenim also did Ring Ding Dong's stage, he even danced to Ring Ding Dong at the end"
Fascinatingㅋㅋㅋㅋ
