As I'm only 18, this was kind of difficult lol, but here are some idols younger than me!
Yugyeom of GOT7 So he's only like 4 months younger than me but he's so adorable! Even if he's also ridiculously sexy and doesn't usually seem like the youngest.
Jungkook of BTS Yeah so even less months between us but it still counts! Also ridiculously adorable!
Hansol (Vernon) of Seventeen Look at this cutie!
