Singer Lim Jae-beom highly praised the live performance skills of girl group F-ve Dolls' Seo Eun-gyo. On the first broadcast of JTBC's variety show "Sing Again - Unknown Singer Season 4" on the 14th, 81 unknown singers performed in the first round of the finals. On that day, contestant number 67 appeared in the "Sugarman" episode with the keyword "Sumdeutmyung," drawing attention.

Contestant number 67 introduced herself as a former girl group member, saying, "I was 20 years old right after the group disbanded. I debuted 14 years ago. Actually, many people know our songs but don't know the singers. I hope people remember not only the songs but also our members." She chose the song "Ireokung Jeoreokung" and showcased powerful dance moves along with outstanding live singing skills.

Contestant number 67 flawlessly performed the rap part alone, filling the stage. The judges could not hide their surprise. She earned 7 "Again" votes, securing her advancement to the second round. MC Lee Seung-gi admired, "She's just an active artist." Lim Jae-beom praised, "She's not human. 'Sumdeutmyung' feels like a song that suffocates you while listening and shortens your life. Watching her handle an idol stage alone was breathtaking; I couldn't breathe, and she did so well."

Kim Eana said, "She's really good. 2011 was a time when many 'Sumdeutmyung' songs were born. It was the era when removing the backing track (MR) was popular, so powerful vocalists with great singing skills performed addictive melodies. She did the whole song alone, including the rap. She proved she's a true master of the 'Sumdeutmyung' era," praising her without reservation.

Kyuhyun also complimented, "There's nothing lacking. She must have been a gem in her team. She's a live singer. I watched in awe, completely captivated." In this way, contestant number 67 successfully completed her stage, receiving praise from the judges for her outstanding skills.
