On August 7th, Super Junior's Heechul showed off his close friendship with fellow member Eunhyuk and f(x)'s Sulli by posting a picture through his Twitter. Heechul tweeted, "The members, staff, and fans worked hard and were awesome. With 21C best friend Hyukjae and Sulli-shalli-sholli-shooli. Also, if you see, compared to the size of my eyes, my eyeballs are really small." In the picture, Sulli is displaying a more mature look with her straight brown hair and blunt-cut bangs.  Heechul also displays his mature charms by intensely staring into the camera wearing smoky make-up with his hair partially covering his face. Eunhyuk, on the other hand, poses differently from the other two with a bright smile on his face, rather than a strong charisma expression. Netizens said, "SM siblings have come together", "Wow, your charisma is no joke", "Ahh, I envy Sulli", "It's good to see the friendship among the three of you!", and "Super Junior's 5th album is awesome."
