On the November 25 episode of the MBC singing competition 'Mask King,' eight new contestants battled for a chance to overthrow the reigning champion 'Chestnut Bread'!
The fourth battle of the episode was between 'Swan' and 'Eagle,' who performed Toy & Kim Hyung Joong's 2001 single "Good Person" for the audience.
During their time on stage, 'Swan' charmed the crowd with her aegyo voice, her sexy voice, and her skillful R&B dance moves, while 'Eagle' made the panel laugh with his impressions of various celebrities. After the audience vote, it was revealed that 'Eagle' beat 'Swan,' meaning 'Swan' had to drop out of the competition and reveal her identity.
The audience was surprised to find that 'Swan' was none other than MAMAMOO's Moon Byul. The idol took off her mask and then performed a fun cover of Zion.T's "The Song."
