1Team Members Profile


1TEAM Rubin

Born on August 16, 1995, Rubin (birth name: Lee Hae-Joon) is a South Korean singer whose public musical stint dates back to 2017 when he joined his first idol reality survival show BOYS24. He was also a member of the group, BOYS24, before their debut. Although Rubin was a member of the show’s Red Unit, he failed to make it into the top ranks and was eliminated by fans vote.

Nevertheless, Rubin parleyed his popularity on the show to join another idol reality survival show in October 2017, MIXNINE, where he made it to the top 9 ranks with plans to debut into a new boy group. For reasons we’re yet to know, MIXNINE’s debut was canceled. It is believed that the decision to cancel stemmed from disagreements concerning contract lengths between YG and the individual companies of the trainees. In December of the following year 2018, Rubin was unveiled as the lead vocalist of the five-member, boys-only group, 1TEAM.



BC was born—Jin Sung-ho—July 18, 1994. It is believed that BC stands for the initials of his other names, Bryan Chin. He debuted in 2013 under the stage name Ra.E. Then, he was part of the all-boys group I-REX signed under Tarzan Entertainment. I-REX had a lot going on at the time it was newly formed and even released its debut album, Rush To The Top, which became its only album released before disbandment in 2014. In 2017, BC contested alongside Rubin on the idol reality survival show, BOYS24, and like Rubin, he was also a member of the pre-debut boy group.

Results from fans’ vote put BC as one of the nine finalists on the boy group. BC later left the group owing to opposing musical points of view. Like Rubin, BC also appeared on MIXNINE and emerged in 15th place when he got eliminated in the 13th episode of the show. On December 17, 2018, he was introduced as a rapper on the boys-only group TEAM LWZ (later known as 1TEAM).
