Hallyu stars Choi Si-won of Super Junior and Changmin of TVXQ began their mandatory military service Thursday.

“Respecting their wishes for a low-key enlistment, there will be no special event for fans or reporters at the site,” said SM Entertainment, the agency that represents the two stars.

The two stars enlisted at an Army training camp in Nonsan, South Chungcheong Province, where they will receive basic military training. After the training, they will serve as conscripted police officers. According to reports, Super Junior members Lee Teuk and Kyuhyun accompanied them to the site. Although there wasn't an official admission ceremony, Super Junior and TVXQ fans still gathered outside the camp to see the singer enter the service.

They are tentatively scheduled to be discharged on Aug. 18, 2017.

Changmin, 27, on Wednesday released a video of him shaving his own hair for the service. Towards the end of the clip, he said he will be back safely.

Choi, 28, who recently starred on hit rom-com “She Was Pretty” on Wednesday said, “The weather is getting cold, be healthy and I will return safely,” through a telephone call on variety show “Radio Star.”

All able-bodied men aged 18-35 must serve in the military for about two years in a country that is still technically at war with North Korea.
