ONEWE
ONEWE (원위) is a five-member South Korean rock band under RBW Entertainment, consisting of Yonghoon (vocals), Harin (drums), Dongmyeong (keyboard), Giuk (bass, formerly CyA), and Kanghyun (guitar). The group officially debuted on May 13, 2019 with the mini album Planet Nine: Alter Ego, but their roots stretch back to 2015.
The members originally formed as M.A.S 0094 (Make a Sound 0094), an independent group that performed public covers with all profits donated to charity, including comfort women victims. Their debut single "Butterfly, Find a Flower" (August 2015) set the charitable tone that defined their early career. The group moved to RBW in April 2017 as MAS, then rebranded to ONEWE in June 2018 before their formal re-debut the following year. This background gave them years of live performance experience before ever stepping onto the idol stage.
ONEWE stands apart from the typical K-pop group model: all five members play instruments and actively participate in songwriting and production. Their sound blends alternative rock, ballad, and indie pop, drawing comparisons to Korean rock acts while maintaining melodic accessibility.
Notable releases include the Planet Nine mini album series across 2019-2024, the 2020 single "End of Spring," and "Rain to Be," which became one of their signature fan-favorite tracks. Dongmyeong is also known as the twin brother of ONEUS member Xion.
ONEWE maintains an active Japan fanbase, regularly touring there alongside their Korean activities.
