ATBO 소개

ATBO (At The Beginning of Originality) was a South Korean boy group formed by IST Entertainment through the 2022 reality survival show “THE ORIGIN – A, B, OR What?”. The group made their official debut on July 27, 2022, with the extended play 'The Beginning : 開花' and their hit single "Monochrome (Color)". Originally a septet consisting of Oh Junseok , Ryu Junmin, Bae Hyunjun, Seok Rakwon, Jeong Seunghwan, Kim Yeonkyu , and Won Bin, the lineup shifted to six members when Seok Rakwon departed in May 2024 due to health concerns.

Throughout their career, they built a dedicated fanbase called "BOAT," showcased their versatility on competition shows like Peak Time and Road to Kingdom, and briefly united with the group JUST B to form the project unit The CrewOne in mid-2024. Following the mutual termination of their exclusive contracts, ATBO officially disbanded on December 17, 2025, concluding their active journey as a group.
