Now, you might be wondering what it's like to have a brother who's a global superstar - I mean, does Jung-hyun get free BTS tickets for life or what? Sadly, Jungkook hasn't spilled the beans about their relationship, but I'm sure it's pretty awesome to have a brother who's a K-pop icon!
But here's a fun fact: did you know that Jungkook's name actually means "strong and PRECISE" in Korean? Maybe that's why he's so good at dancing and singing - it's in his name, folks! And who knows, maybe Jung-hyun has some hidden talents too (maybe he's a secret chef or something?).
