Moon Je Hyun, known mononymously as Jehyun, is a South Korean singer, dancer, former member of 1TEAM and current member of OMEGA X. He graduated from global Cyber University with a bachelor's degree in Broadcasting and Entertainment.

He made his debut in March 2019 as 1TEAM's vocalist and main dancer with their first mini-album, "Hello!". Unfortunately, Live Works Company decided to terminate all the members' contracts and 1TEAM disbanded a few weeks before their first anniversary.

After switching agencies, he re-debuted in July 2021 as a member of OMEGA X with their first single album, "Vamos". However, in October 2022, a video of the CEO of OMEGA X's label (Spire Entertainment) abusing him and his group members came to light. The members filed a lawsuit against their company to cancel their exclusive contracts and to file for the trademark of their group name. In January 2023, OMEGA X won the lawsuit and officially ended their contract with the agency. This was finally made official on May 8, 2023.

The group has been represented by IPQ since July 2023.
