On one recent episode of NAVER NOW's radio show 'One Guy in Town (literal translation)', Kim Jae Joong shared an interesting story.

When one listener asked if that card he had was 'the Black' from Hyundai card, he answered, "Yes, it is."
'The Black' is a credit card for the super rich; only a small number of people own this card in Korea.
Available through invitation only, the holder of the card has to be personally approved by the vice president of Hyundai Card and seven members of board of directors.
The holder should have 100 billion won (approximately 83 million dollars) earnings and savings, and has to pay the annual membership fee of 2 million won (approximately 1,700 dollars).

He continued, "After discovering that, I was like, 'Oh, it's so cool that I have the same card as BTS members!' It made me really excited for some reason."
He went on, "I never used to boast about having 'the Black', but these days, I've been showing off to people around little by little."
Then, Kim Jae Joong wrapped up the story by sending a finger heart to BTS while saying, "I love you guys, BTS!"
