“Left and Right,” a breezy pop track about yearning over ex-love, marks Charlie Puth’s first official collaborative release with BTS‘ Jung Kook.

The song was first teased on Charlie’s TikTok on February 25, 2022, originally as a solo song. Two months later, Charlie tweeted teasing ‘a dream-collab with BTS’ on the “Left and Right.” At the beginning of June 2022, he started again dropping several hints in his TikToks, this time specifically for a collaboration with Jung Kook. Around two weeks later, the song was officially announced on Puth’s social media, with a video of him and Jung Kook working on the song.
