In a recent interview regarding her drama 'The K2', YoonA talked about her members and said, "We tend to monitor for one other when someone films a drama or makes a comeback. They take photos of themselves watching the first episode and share it on our group chat. Some also ask about how the story will go here and there."
When asked if Yuri and Sooyoung, who've also done dramas, ever give her advice on acting, YoonA answered, "We don't talk about acting related things. We rather talk about looks and make suggestions about outfits, hair, and makeup."
