A new JPop group is debuting soon and this guy here turns 28 in 13 days:
I bet KPop would scream and cry if someone born 1995 would debut these days. Most of the KPop-fandom allready cried when someone debuts who is older than the birthyear of 2000
And hey, being 20+ of age is not bad, cause you arn't to old and most likly allready got enough training in comparisom to other people, maybe you also worked in another field of the entertainment industry before that helped you to gain all the knowledge you need to debut as a proper idol.
But oh well KPop-fandom will cry if you debut and revel yourself as in your 20s ...
