When he introduced himself, he revealed that he had half a line during their debut song. He said, "People looked down on me a lot, and would tell me, 'Do you really have to rap?' But I thought that if I wanted to change that way of thinking, I had to be responsible, grit my teeth, and do it." San E agreed that the stereotype of 'idol rappers' used to be that they weren't very good, but now that it was different and that he just had to prove himself.

Hwiyoung started rapping and immediately impressed the other contestants of the show. One of them said, "Even though I hadn't experienced the idol life, he rapped it so that I sympathized with it." 

The judges were equally impressed. Hangzoo said, "Your tone was very nice. Some rappers make a living with their tone. I think you are one of those rappers. When you had those four lines during the intro, I was very surprised. As I said before, I think that instead of other people having stereotypes, the idol rappers have a stereotype on themselves. I think you don't have to think like that at all." 

Deepflow was similarly impressed, saying, "I thought you would have a trap beat with electronic sounds, and overly strong lyrics. But the beat was completely different from what I expected. Your rhythm and voice tone were very charming. I thought to myself, I actually did have a stereotype. You were very cool."

Groovy Room's Kyujeong said, "You came out to prove yourself, and I think you did. Stop calling yourself an 'idol rapper' and just say you are a rapper. I think you can ignore the people judging you."
