Super Junior's
Donghae and
Eunhyuk made their
debut performance on
Music Bank with their latest duet song "
Oppa Oppa", and their fellow member
Siwon came to cheer for them.
On December 16th, Siwon transformed into an ELF and joined the crowd screaming loudly for their oppas. He took a photo and uploaded it on his Twitter with comment, "Donghae and Eunhyuk are pre-recording the show! I’m an ELF today ^^! Everyone, Oppa is here~^^!"
In the photo, Siwon can be seen holding a blue balloon while sitting along with other ELFs.
