On the special for composer Ahn Chi Haeng, Lovelyz faced their admitted "uncle fans" No Brain. No Brain's Sung Woo expressed, "To be honest, I really like Lovelyz a lot. It's an honor to participate in the show with them."

The girl group covered legendary singer Na Hoon Ah's past hit "Yeongdong Blues", and their lovely, fresh rendition of the song won favor with the audience. No Brain ended up winning the round, and it was Lim Jung Hee who took the final win.

Congrats to No Brain!
