On December 17, Jang wrote the comment on his me2day account, “I’m on my way back home. Awesome, IU! You are so good at the joint dance. Let’s dance together!”
This seems to be a response to IU’s imitation of Jang’s high-level joint dance shown in the episode of KBS 2TV’s Yoo Hee Yeol’s Sketchbook that aired on December 16.
In the episode, IU imitated Jang’s joint dance performance from his song “Time Is Over” without much difficulty, freely moving her head, neck, and shoulders.
People responded: “If Jang Woo Hyuk has recognized IU’s dance, IU is really good at dancing,” “I watched it too, and she was really good.”
