Background
Kim Dong Hyun, better known by his stage name Leehan, was born on October 20, 2004, in Busan, South Korea. Before pursuing a music career, he trained as a taekwondo athlete, developing the discipline, balance, and body control that would later contribute to his performance skills. His athletic background helped shape the clean movements and strong stage presence that fans often praise today.
In 2023, Leehan debuted as a member of BOYNEXTDOOR under KOZ Entertainment. While known for his stable vocals and graceful performances, he has become equally famous for his unique hobbies and gentle personality. His love of aquascaping, fishkeeping, and marine life has made him one of the most distinctive members in the group, earning him a reputation as BOYNEXTDOOR's resident nature enthusiast.
