K-pop groups often have large age gaps between the eldest and youngest members, but that has never stopped them from getting along. In fact, sometimes an older member of the group can easily pass for the maknae in various situations, mainly due to their adorable, childlike behavior.

Because age is just a number, here are 10 K-pop idols who are so young at heart, we could simply mistake them for being the youngest in their group.

1. BTS’s Jin

If Jungkook is the group’s youngest member, Jin is the unofficial maknae thanks to his babyish attitude. He’s often seen fooling around, and his members have no choice but to keep up with him.
