For the special featuring songs by composer Ha Kwang Hoon, Kangnam covered Byun Jin Sub's "Becoming Alone" as the fourth performer up. He expressed, "My mom is a fan of 'Immortal Song' and watches often. This song is my mom's favorite. I've heard it since I was younger, so I chose it. If I fail, it's my mom's fault."

Kangnam added, "Kangnam is a singer. I'll work hard to show you a good side of myself." When he went on stage, he was obviously nervous, but once the song started, Kangnam impressed everyone with his steady vocals.

It was B1A4's Sandeul & Lazy Bone (Highlight for Spoiler) who took the final win.
