Super Junior's leader Leeteuk will conclude his official activities with recording of SBS "Strong Heart" before his army service.

Leeteuk's filming of the show will mark his final official schedule prior to his enlistment for his 2-year mandatory military service.

Leeteuk has been a fixed member of "Strong Heart" since 2009. He was enthusiastic in the program that he only missed two shows despite his busy personal and group schedule with Super Junior for three years.

The production staff stated that "Leeteuk will record the episode of 'Strong Heart' on the 25th. That will be the last schedule before going in to serve the army."

"Strong Heart" staff will provide a good bye event for Leeteuk. Park Sang Hyuk PD showed special affection towards him saying "I wish 'Strong Heart' could work with Leeteuk when he comes back."

Leeteuk will serve in the army for 2years starting on October 30.
