Boy With Luv (feat. Halsey)

"Boy With Luv" is the cheerful companion to 2014's "Boy In Luv." Where the earlier track was an aggressive teenage crush, this song celebrates the simple joys of being in love — wanting to know everything about the person you care for. The collaboration with Halsey and its bright, retro-pop production made it BTS's biggest hit at the time, with the music video setting the record for most-viewed YouTube premiere.
