-I can't believe Red Velvet is already going to be 10 years old... Unbelievable
-Hul... GFriend would've been 9 years old next year...
-I still can't believe TXT is going to be 5 years old already...
-BTS is 11 years old... 11 years...
-Aespa will be 3 years old next year...! They haven't even celebrated their 2nd anniversary yet.
-It doesn't make sense that Blackpink is going to be 8 years old. Give us more songs.
-BTS is the only one that's going to be 11 years old? What about the other idols? Didn't a lot of groups debut in 2013?
-Almost none of the idols who debuted in 2013 survived...ㅠㅠ
-TXT is going to be... 5 years old? It feels like they just debuted not too long ago
-Treasure and Enhypen are going to be 4 years old next year? Why do I feel like they're still rookies...?
