1TEAM, a dynamic five-member boy group formed under Liveworks Company, burst onto the K-pop scene on March 27, 2019 with their electrifying debut mini album, Hello!. BC and Rubin brought their prior music industry experience to the group, with BC formerly being a member of I-REX and a contestant on BOYS24 and MIXNINE, while Rubin also appeared on BOYS24 and MIXNINE, making it to the top 9 in the latter show. Originally set to debut under YG Entertainment, disagreements led to their cancellation, but Liveworks Company stepped in and unveiled the talented members of 1TEAM as TEAM LWZ before their highly-anticipated debut in March 2019. Unfortunately, after two years of captivating performances and music releases, Liveworks Company sadly announced the disbandment of 1TEAM in March 2021 through their fancafe. Rest in power, 1TEAM - you will always be remembered for your incredible music and performances.
