It's been a little over a week since Super Junior's Donghae and Eunhyuk were enlisted in the army.

However on Thursday, October 29, Leeteuk revealed that he wrote letters to the two members through his Instagram post.

The photo was a collage of Leeteuk with Donghae, Eunhyuk, and two envelopes respectively for each enlisted member.

"I wrote letters to these two after my schedule," Leeteuk said in his caption. "Is this the heart of a parent with his child in the army? Haha I miss you my little brothers.. Ah.. Have to wake up soon~." 

Eunhyuk entered the army on October 13 and Donghae on October 15.
