Zeon
Zeon (제온; real name Park Jae-hoon, 박재훈) is a member and lyricist of South Korean boy group TUNEXX under IST Entertainment. Born July 20, 2005, in Nowon-gu, Seoul, South Korea, he is the group's resident fox (representative emoji: 🦊), with songwriting instincts that announced themselves from day one.
Before TUNEXX, Zeon competed on The Origin - A, B, Or What? (2022) - IST Entertainment's in-house survival show - before being eliminated in episode 5. He had previously trained under Fantagio Entertainment, building the kind of patient craft that multi-stage audition circuits demand. His blood type is A and his MBTI is INTP.
On the creative side, Zeon co-wrote debut title track "Proof That I Am Alive" alongside leader Donggyu and member Sihwan - making him one of three credited writers in the group from the very first release. He also recorded "Rhapsody," a pre-debut drama OST for the Korean series Moon River, with members Sihwan, Taira, and Sungjun.
Off-stage, he is known for a low-key, thoughtful demeanor - an odd contrast to TUNEXX's aggressive punk-inflected debut aesthetic. His family includes an older sister. TUNEXX debuted March 3, 2026, with their first mini-album SET BY US ONLY.
