Super Junior's Leeteuk (Park Jung Soo) recently posted a photo on Instagram taken with Choi Siwon, who is one of several members of the group enlisted for their mandatory military service.
"It's snowing and everyone is saying it's pretty but snowing sucks when you're in the army," wrote Leeteuk on Instagram. "I'm worried for our Donghae, Eunhyuk, and Siwon. They're going to think it's trash falling from the sky."
"It's getting cold," he continued. "All soldiers dress warm and thank you for your service!"
Addressing the pictured Siwon directly, he added, "I saw on the internet that the reason [your nickname] Ten is that it's our tenth debut anniversary this year haha miss you a lot."
In the posted photo, Leeteuk is smiling for the camera with Siwon. Siwon is also smiling brightly, with his head shaved for the army.
