Sojung blew everyone away with her cover of Lim Jae Bum's "Beautiful Misunderstanding". MC Jung Jae Hyung commented, "She sings so well," while Moon Myung Jin said, "During rehearsals, I heard her voice from the waiting room and ran out to see who it was. She's very talented." ALi also mentioned that she was proud to have a hoobae like Sojung.

Despite how much the crowd loved Sojung's husky, powerful voice, B1A4's Sandeul took the final win.
