Woo Je Won, known mononymously as Jewon, is a South Korean singer, dancer, and member of NINE.i (나인아이). He graduated from Hangwang High School and, before debuting, spent time as a trainee at Around Us Entertainment and two more years at FirstOne. He was also a backup dancer for BTS.

He made his debut in March 2022 as the group's leader and vocalist with their first mini album, "New World".

However, in March 2024, all members (except Eden) became involved in a legal dispute with their agency, FirstOne Entertainment (퍼스트원 엔터테인먼트), for undisclosed reasons. In June of that year, the issue was resolved, but they went on hiatus to plan their future activities.

In December 2024, they made their debut in Japan with the single "Mirage". They will continue to promote there, as they are currently without a South Korean agency to manage them.

He enlisted in the military on June 19, 2025.
