Super Junior's Donghae and Eunhyuk held their debut stage on 'Music Bank' today for�their duet song "Oppa Has Arrived", and they received some support from fellow groupmate, Siwon! For a few hours, Siwon became an ELF screaming loudly for his 'oppas' from the crowd. He took a picture with Super Junior's fans in the audience, and tweeted,�"Donghae and Eunhyuk are pre-recording! Today I am also an ELF�^^! Everyone, Oppa Has Arrived~^^!" ELFs around the world writhed with envy, and left comments like, "Why couldn't I be there!! T__T", "Siwon's humility... so proud to be a fan", and "Super Junior, fighting!" Source + Image: Siwon's Twitter
