Like a mother who can't help but worry when sending her children off to college, Super Junior leader Leeteuk expressed his concern over his dongsaengs, who are currently serving in the military. 

On his Instagram, the singer shared a cute picture of himself and Siwon smiling happily with their heads close together. 

Along with the picture, Leeteuk wrote, "When it snows everyone says 'so pretty,' but when you're in the army all you can do is sigh. I worry about our Donghae, Eunhyuk, and Siwon. The days are getting colder. All the soldiers and servicemen, please take care of your health and work hard!" 

Aw, don't worry too much Leeteuk. Your dongsaengs are all grown and they will be back by your side before you know it!
