Super Junior singer Kim Heechul completed his mandatory military service in the South Korean Army on Friday, at the same Seongdong District Office where he enlisted and has been stationed for the last two years.

And by the looks of things, he's pretty happy about it.

Flashing an award of honor he received for the high quality of his work, Heechul grinned ear-to-ear as he left the Seongdong facility for the final time.

"While he was on duty at the Seongdong District Office, Kim Heechul has been a model employee and worked hard in the radio program put on by the District Office," an army statement reportedly read, according to the publication eNEWS.

Hours after his release Heechul went on an Instagram rampage, posting over a dozen images to the photo-sharing site and promising to post 100 more.

In the shots, the Super Junior singer appears to be enjoying his newfound freedom as he drinks coffee at a Tom N Toms and dines with friends.

Heechul was not eligible for standard army duty after a major car crash in 2006 left his leg permanently damaged.

The accident happened when the singer was on his way back to Seoul from a funeral service for his Super Junior bandmate Lee Donghae's father in the city of Mokpo and his tires reportedly malfunctioned.

Heechul's leg was broken in five places, and required eight metal rods to be surgically implanted in his leg.

Although the rods were removed by 2008, the South Korean National Ministry of Defense, deemed the singer to only be fit for desk duty.

All eligible males between the ages of 18 and 35 currently must enroll for between 21 and 24 months of army service in South Korea (the length of mandatory enrollment changes by several months depending on which branch of the military that they serve in) in a practice known as conscription.

Heechul, who enlisted on September 1, 2011, began hosting a Seongdong District Office radio show in January of last year.

According to a representative from Super Junior's record label S.M. Entertainment, the singer didn't want any big events marking his return to civilian life, but he is apparently eager to rejoin his 11 Super Junior bandmates on the road.

"Heechul will take a brief vacation, and will join the Super Junior members for their ongoing world tour," the S.M. representative told the Korea Star Daily.

"But as for other activities, we will have to discuss them in details with him at a later date."
