While listening to their new title track "Boy With Luv," the members shouted out Halsey's name and thanked her for the collaboration.
BTS said, "We didn't know Halsey will actually come to Korea but it turns out she actually comes often. That day (of filming) was very nice." j-hope added, "There's a scene where she dances with us. She already practiced before coming. She worked so hard I was touched." Jimin also said, "She was very nervous but I was thankful for her hard effort."
