On June 29, 2021, girl group Black Swan's agency DR Music announced, "After posting a global online audition notice recently, nearly 4,000 applications have gathered." DR Music plans to bring the final selected people from the first audition to South Korea and have them survive through intense training.
Black Swan debuted last year but soon halted their activities due to a scandal of former member Hyeme who eventually left the group after her contract's termination.
Black Swan are confirmed to be making an August comeback with the addition of a new fifth member. More details of the identity of this new member are expected until then.
Until now, Black Swan has attracted attention through their own domestic travel YouTube series 'B'LIT'. Currently, Black Swan's official channel has almost 400,000 subscribers, 90% of whom are fans living abroad.
