Singer-songwriter Jeong Se-Woon celebrated the 4th anniversary of his debut with Lucky (official fan club name).

On August 31st, a special choreography video of his debut song "Just U" was released on Jeong Se-Woon's official YouTube and Naver V LIVE channels.

In the released video, Jeong Se-Woon's appearance at the time of his debut four years ago shows off his rookie-like freshness, while adding fun to watching with a stand microphone and colorful large-sized choreography composition.

In particular, this video is a special gift as well as recalling memories of fans on the fourth anniversary of their debut by adding choreography using a sofa, not just "JUST U," which Jung Se-Woon previously showed.
