Two members of Super Junior will say goodbye to fans ahead of their military enlistment.

Super Junior's Donghae (Lee Dong Hae) and Eunhyuk (Lee Hyuk Jae) will perform at a festival in Seoul on Oct. 4. It will be the pair's final performance before they enlist later this month.

Donghae and Eunhyuk, also known as the Super Junior subgroup Super Junior D&E, will perform at the 2015 Gangnam K-Pop Festival.

The Oct. 4 performance is set to be part of the farewell activities for Super Junior D&E. Eunhyuk will enlist in the Korean Army as an active duty soldier on Oct. 13, while Donghae will begin serving as a conscripted police officer on Oct. 15.

Super Junior D&E will perform at 7:30 p.m, and will be joined at the festival by other SM Entertainment artists, including Super Junior M members Zhou Mi and Henry, Red Velvet, and EXO.

All able-bodied Korean men have to serve a period of around two years in the Korean military.

Donghae and Eunhyuk are the seventh and eighth members of Super Junior to enlist in the military. They will join Super Junior's Shindong and Sungmin, who are currently serving.

Another member of Super Junior, Siwon, will also enlist before the end of the year on Nov. 19.
