Super Junior's Eunhyuk celebrates his birthday with his members and f(x)

Super Junior's Eunhyuk celebrated his 24th (in Korean age) birthday with his members and his junior. I guess the SM Family has a strong bond because these cuties all got together for Eunhyuk's birthday despite their busy schedules. Though only Luna of f(x) was there, it shows they are all really close. Shindong uploaded pictures onto his Twitter and got the netizens excited. In the picture, Eunhyuk looks like he got a cake squished in his face. They all look very casual so it definitely wasn't a big grand party where only top celebrities got invited. They are quite down to earth I guess. Luna showed her politeness towards her senior with a handwritten card. Shindong joked, "Luna is so nice. Eunhyuk is thankful. But I guess you made this really fast." Oddly, there is a foreigner in the picture as well as someone who seems to be Korean but isn't a Super Junior member. Maybe this could mean they're working on a new project such as a comeback? I doubt it though because of the problems with Hangeng and since Kangin has been pretty MIA as well. Nonetheless, Happy Birthday Eunhyuk!
