In the first round, the singer who appeared as 'Terius' sang a duet with 'A Little Princess' which was aired last week. They melted the hearts of everyone with their soft, angelic voices.

After moving on to the second round, 'Terius' held a solo performance as he covered hyukoh's "Comes and Goes". He, once again, flawlessly carried out the song with his beautiful vocal tone, despite the song itself being extremely difficult. 'Terius', however, lost in the round against 'Drum Man'.

It was now time for 'Terius' to reveal his true identity. As he did so, the audience and the panel alike were taken back to see Wanna One's Minhyun! Kang Daniel was the only to not be shocked to see his fellow member on the stage and said, "He's in our group. There's no way I would not have known." He also added later, "The way he's standing up, I see that every day. His voice is something I can't forget."

During the interview, it was revealed that this was the first time in which he held a solo stage since making his debut. Minhyun explained, "There are many instances where I have to sing based on the directing given to me, in order to fit the team's color. There aren't too many opportunities where I can sing songs I prefer. In the past, I remember uploading clips of me singing songs that I wanted to on SNS but ended up deleting them because I was embarrassed. I really wanted to come on 'Mask King'."
