Seo Eun-kwang
Seo Eun-kwang (서은광; born November 22, 1990) is a South Korean singer and the leader of BTOB. His stage name Eunkwang became synonymous with one of the most technically refined voices in fourth-generation K-pop -- a singer equally at home in stadium pop and musical theater.
Born in Seoul, Eunkwang debuted with BTOB under Cube Entertainment on March 21, 2012. From the group's earliest releases, he anchored the vocal line with a power and emotional precision that set him apart. His solo career launched in 2020 with the mini-album FoRest: Entrance.
Beyond recording, Eunkwang has built a parallel career in musical theater, appearing in productions including In the Heights and various Korean stage productions. He hosted MBC Every1's Weekly Idol from 2023.
Following BTOB's departure from Cube Entertainment in November 2023, Eunkwang signed with BTOB Company -- a sublabel under DOD Entertainment established for the group's continued activities.
