On the February 24 episode of 'Yoo Hee Yeol's Sketchbook', producer and writer Kim Hyung Suk made an appearance, with the help of some artists from the same company. They started off by performing "First Impression", "Na Na Na", "Get Up", and "Right?", which were all produced and written by Kim Hyung Suk himself.
During the interview segment, MC Yoo Hee Yeol mentioned how some of the songs listed are from the '90s but also that Killagramz is from the United States which may have made the songs unfamiliar, which resulted in him in asking the rapper his age. Killagramz answered, "I was born in 1992. I'm the same age as Zico and DEAN." As he said this, the audience couldn't hide their surprise at the revelation and Yoo Hee Yeol even joked, "Oh...why...why were you born in 1992...?"
