-They're all from the 2nd Generation...

-Sechs Kies too~~

-I thought I would see Celeb5 in this postㅋㅋㅋㅋ

-My favorite idol group is from the 3rd Generation and they're also not wearing name tags when they guest on this show

-Oh, I think I get it... I know all of their names even when they're not wearing name tagsㅋㅋㅋ Anyway, what is BTOB doing in that pictureㅋㅋㅋㅋ

-Yeah, because we know all of their names...

-My bias didn't have his name tag on when he guested with another actors/actresses, but he had his name tag on when he guested with his groupㅋㅋㅋㅋ

-I know the names of all idols in this post, with no exception

-DBSK also didn't have their name tags on when they guested on this show. I guess idols from 2nd Generation don't need them anymore...

-I think if the casts already know all of their names, they won't be using the name tags...? Or it depends on their popularity among the general public?

-I think they don't need to wear the name tags if the casts recognize each of the member...

-I see... I'm familiar with all of their names and facesㅋㅋㅋㅋㅋ

-Because idols from 2nd Generation are already doing solo activities by now...

-Red Velvet didn't have their name tags on the last time they guested on this show!
