On March 27, Liveworks Company's first ever boy group 1TEAM held their debut showcase at the K-Art Hall in Seoul's Olympic Park.

1TEAM members Rubin and BC previously made their names known as contestants on JTBC's 'MIXNINE', with leader Rubin even making the final debut team. However, the winning team's debut was ultimately cancelled. 

Regarding the incident, Rubin revealed, "Many people know me as 'MIXNINE's Rubin. I made it into the final debut team lineup, but the team's debut was cancelled. To be honest, I was sorry to hear about it, but knowing that my team members who are like 'The Avengers' were waiting for me back at the company, I wasn't disappointed. I am working hard. So I hope that people will call me 1TEAM's Rubin from now on, and not 'MIXNINE's Rubin." 

1TEAM will be making their debut this March 27 at 6 PM KST with their 1st mini album 'Hello!'.
