It's shocking to see those born in 2013 debuting as idols

‌Those born in 2013 are 14 years old
Since the year is about to change, they are debuting at nearly 15
Wonder Girls debuted at 15
Come to think of it, it was like that 20 years ago too
Karina was born in 2000
Jang Wonyoung was born in 2004
There is a 13-year and 9-year age gap with them respectively
I remember searching for Jang Wonyoung when she was causing a stir on Bulpen
and she was 15 at the time
Already about 10 years have passed...
Time is flying by incredibly fast
