Halsey did an amazing job with the dance for "Boy With Luv," but did she have any trouble keeping up with the moves? BTS answered the question in an interview with iHeartRadio.
RM first let out a laugh and said, "You know Halsey. She's always confident, powerful, and cool. When she came to Korea and we met for the MV, she was like a tiny bird. (She said) 'I'm nervous. It's my first time ever dancing officially.'"
RM praised Halsey's hard effort and said, "She practiced so hard... She showed what she practiced to our choreographer, and asked, 'How am I?' (The choreographer said) 'Oh my god, you practiced'," and applauded her.
