It's a happy day because it's the birthday of Super Junior's lovable Shindong! September 28 marks Shindong's 30th birthday (31 in Korean age)!

He posted a photo of himself on Instagram looking super happy holding up a birthday cake he received from the SM family! We're sure fans were very happy to see his face again as he is currently carrying out his military service.

He also brought chuckles to fans as included with his post were hashtags, "#EunhyukDonghaeSiwonChangminEnlist #I'llBeSureToNagYou".

Be sure to congratulate Shindong!
