NiKa, a Bad Kids member, teamed up with the Tetogirls for a stage in the Era of Classics round but could not advance

NiKa, the wife of singer Kim Hyun-seong and a member of the girl group Bad Kids, failed to advance to Round 3 on JTBC’s Sing Again 4. On the November 11 episode, female vocalists faced a big match in the Round 2 team battle. In the Era of Classics Team Battle, contestant 6 and contestant 43 NiKa formed the Tetogirls and performed Mamamoo’s Piano Man, delivering a rhythm-rich stage that drew attention.

Code Kunst praised the collaboration, noting that the team performance came together well and that NiKa’s presence added to the ensemble. However, the duo lost to the only team of contestants 25 and 61, failing to reach Round 3. NiKa said the broadcast was both a heartfelt opportunity and a daunting moment; overcoming that fear made her proud, and she vowed to continue growing as an artist who can take another step forward.
