KIM JAE HYUN is N.Flying’s drummer and an original member of the band’s early lineup. FNC identifies drums as his instrumental role. His career with N.Flying began with Japanese independent activities before the Korean debut in 2015.

His playing provides the rhythmic foundation for arrangements that move between reflective pop-rock and high-energy concert material. His on-screen work is a separate part of his career and should not be counted as a solo music discography.

After the military-service period, the five-member band’s activities continued with Everlasting in 2025 and Still in 2026. The main N.Flying profile contains the shared music videos and wider concert timeline; this page focuses on his place in the band.
