The age that K-Pop idols debut at has been a pretty controversial subject for some time, especially in recent years with groups like NewJeans, BABYMONSTER, and others that have members 16 and younger. It isn’t a recent issue, though, and in fact, there have been many K-Pop groups in the past that haven’t had an all-adult member line-up by the time they debut. These are the only K-Pop boy groups that have debuted with every member being at least 18 years old by international age metrics.
