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!�
