Girls' Generation member Yoona made a brief appearance today on SBS' "Strong Heart" special farewell episode for Super Junior's Leeteuk.

In the episode Yoona shared, "I will visit Leeteuk in the army. Even though he's a leader of Super Junior it feels that he's also a leader of SM artists' as well. I wonder who will fill his role while he is gone."

Finally Yoona delivered a Girls' Generation's signed copy of MR. TAXI album stating, "I hope this will be of help to him. I hope it gives him strength."
