BeatBurger's Jae shared a practice clip of Kai's solo from the incredible '2018 Pyeongchang Winter Olympics' closing ceremony performance.

The choreographer wrote that his "biggest worry was how to showcase a Korean stage. What we thought of after a long debate was the kkwaenggwari, a traditional instrument representing Korea."

He also stressed that they "chose to work with a more free rhythm and free tempo than a systematic, set rhythm and tempo, for the sake of the Korean kkwaenggwari's signature energy."

He finished with, "Unfortunately, this is footage from the second day of practice, and I do not have any other footage of our work, so I am uploading this after talking to Jongin about it."

Watch Kai's practice and process work below.
