Lim Hyunsik is a BTOB vocalist and music writer closely associated with the group’s ballad and songcraft traditions. He has contributed creatively to BTOB recordings while also releasing independent solo music, notably the album The Young Man and the Deep Sea in 2024. His work across songwriting, production and singing gives his solo discography a distinct identity apart from BTOB.

BTOB made its debut on March 21, 2012, and is known for songs such as Missing You, Only One for Me and Beautiful Pain. LIM HYUNSIK remains part of its six-member lineup, while the independently issued solo music listed here qualifies the artist for a separate SOLO classification. Solo releases and group performances are not interchangeable categories.
