SEOUL (The Korea Herald/Asia News Network) - Actor Kim Soo Hyun will enlist on Oct 23, his agency said Thursday.

"Since (Kim) is just fulfilling his duties as a Korean citizen, he wishes to enlist quietly without a fan event or a press conference," Keyeast Entertainment said in a press release.

His popularity skyrocketed after he played an alien in the romantic fantasy My Love From The Star (2013-2014), which also starred Gianna Jun.

All able-bodied Korean men are required to serve in the military for around two years, with some being allowed to serve in non-combat positions.

While he had originally pledged to enlist this year, there has been speculation that his plans may change due to the massive commercial and critical failure of his recent action thriller noir film Real.

He told local media in June that he wanted one last acting gig before enlisting.
