Woonhak

Woonhak (운학), born Kim Woon-hak (김운학) on November 29, 2006, in Suwon, Gyeonggi-do, is the maknae (youngest) and a vocalist and performer of BOYNEXTDOOR, the six-member boy group under KOZ Entertainment. At 182cm and classified ENFP, Woonhak brings a high-energy, expressive presence to the group -- one that earned him the nickname "teddy bear" from fellow member Jaehyun.

Growing up passionate about music, dance, and basketball, Woonhak cited ZICO's "New Thing" as an early inspiration and dreamed of being a rapper, composer, and dancer simultaneously -- realizing K-pop was the path where he could do all three. He debuted with BOYNEXTDOOR on May 30, 2023, with the single album Who!. From July 2023 to April 2024, he served as an MC on KBS Music Show Inkigayo alongside TXT's Yeonjun and Park Jihu, marking him as a recognized emerging face in the industry well before the group's major international push.

Outside BOYNEXTDOOR's discography, Woonhak has fronted brand campaigns including an appearance for BAPE. He is known for his infectious energy, his close bond with all six members, and the way he makes every fan feel like a personal friend.
