Donghae was the one officiating the event, and like the good friend he is, he welcomed Siwon and Changmin warmly on to the stage. They sure look extra handsome in uniform! It's good to see that all three singers are looking well after they have departed for mandatory military service.

The three also performed on stage along with the rest of the Seoul Metro Police's promotions unit, which you can watch in the video above! 

You can take a look at the photos which were taken at the event.
