Sweet Tune produced boyfriend's comeback title song, 'Obsession,' producers who have also produced for Kara and Infinite. The song is an urban hip hop genre and has strong hip hop beats and deep brass.

The song is about a guy who cannot get to a girl's heart and shows the emotions in rough emotions. For a year, Boyfriend worked to show each individual member's characteristics and perfected the sound and choreography.
