-This show was so f*cking fun. It was literally the only thing my friends and I talk about at school.

-I agree. I was not a fan but I know about this program because I heard Kang Seungyoon and Lee Seunghoon were in it. 

-This show was really popular even among non-fans. You know that guy, Nam... He was really popular. 

-I witnessed how popular this show was, probably because I was still in school back then. Everyone at school and the academy talked about this show all the timeㅋㅋㅋㅋㅋ

-I was still in middle school at the time this show aired. My friends and I usually would watch clips of this show during breaksㅋㅋㅋㅋ

-This show aired when I was in 10th grade. There were none of my friends who didn't watch this show. 

-I watched this show because I heard Kang Seungyoon from Superstar K was in itㅋㅋㅋㅋㅋㅋ

-Oh... I was still in primary school at that time, that's probably why I had no memories of it...

-I was in 7th grade when this show aired. My class was divided into 2 different sides to support each team and we used to fight a lot because of it back thenㅋㅋㅋㅋ

-If you were in middle or high school at the time this show aired, there's literally no way you didn't know about this show.

-What year did this show air in? I'm not a K-pop fan, but I know about Produce 101 because it's really popular. But not with this show, it's my first time hearing about it. 

-Popularity? Produce 101 Season 2 had the biggest popularity. 

-Who are these?

-All of the participants in this show are really talented...
