I listen to some kpop songs but not all of them and I’m not too deep into it. You know if something comes by my fyp or feed I’ll take a quick look. I’m on vacation with my uncles family and he has a 10yr old and a 7 yr old and the 7 year old knows the entire dance to hootie fruits? And my 10 year old cousin says baby monster and katseye are really popular which I didn’t know but I guess now I know. I looked deeper and I listened to some other katseye songs and the ones in the beginning were pretty good imo!
So my question is what age group is Katseye for?
