On the July 19 broadcast of KBS "Star Life Theater," Leeteuk and Donghae revealed that their friendship goes way back to thirteen long years. They shared that they had been preparing to debut in a group called "Smile," but things didn't fall through.

Leeteuk shared, "Donghae and I were part of a five member group. However, not far from our planned debut period, TVXQ debuted."

He continued, "Our agency pondered, 'What should we do with these two teams.' There was obviously some tension between the two groups. Eventually TVXQ debuted and ours didn't." He shared the difficult consequences they had faced following the decision.

On this broadcast, Leeteuk also revealed Donghae's love for working out. He shared, "Donghae never forgets to go to the gym every single day. Even when he finishes his schedule in the early morning, he still calls me to join him at the gym."
