On the March 21 airing of MBC's 'Radio Star', Park Woo Jin revealed that his younger sister is a fan of BTS. This leads to fights in the family as his mom demands they watch shows with her son, while his sister wants to watch the ones with BTS. 

However, Park Woo Jin said, "But she did tell me she has it easy at school thanks to me."

The MCs commented, "It's because she sees you all the time at home", and Seungri also said, "My sister has a trauma about being Seungri's dongsaeng. She hates it."
