Kim Soo-hyun began his mandatory military service without a ruckus Monday.
The actor entered an army training centre located in Paju, Gyeonggi Province, around noon.
Kim arrived at the site in a black van and entered the centre without addressing the crowd of some 40 international fans, who had been waiting at the entrance of the centre since morning.
Kim's management agency Keyeast Entertainment had previously said that Kim did not plan to address fans or the media prior to the start of his service. "We did not want to seem particularly noisy," the agency said.
Having suffered a heart condition as a child, Kim had been assigned to nonactive service as a public service worker after a physical examination in 2012. However, the actor worked to improve his health in order to be posted to active duty.
In 2015, after a second checkup, Kim was deemed fit for active duty.
The actor is known to international audiences for his roles in drama series such as "Moon Embracing the Sun" (2012) and "My Love from the Star" (2013). He most recently starred in the psychological thriller film "Real" (2017).
After five weeks of training, Kim will be assigned to a unit and will serve for 21 months. Kim is scheduled to be discharged on July 22, 2019.
