Super Junior's Kim Heechul uploaded a selca of himself together with fellow member, Donghae and f(x)'s Sulli recently and it caught the attention of netizens. Super Junior and f(x) are brother and sister groups under the SM Entertainment label and the selca was uploaded on Heechul's Twitter on the 14th where he wrote, "Pretty idols~ If Hongki was here as well it'd be perfect!" There is some sort of link between Heechul, Hongki and Sulli as the previous two were former MCs of Inkigayo while the latter is the current MC. Nevertheless, Super Junior will be making their first comeback stage tonight on Music Bank. Stay tuned on allkpop for the performance! Oh, f(x) too!
