Director Bardia Zeinali has kept things surprisingly rooted in reality for Troye Sivan's duet with the ubiquitous Ariane Grande.

Troye takes the mic in a communal room, barely gaining a flicker of interest from the onlookers - and when he's joined by Ariana and the two become immersed in their duet, the room actually empties.

Their dynamic duet is in such remarkable contrast to their mundane surroundings, and of course that's the point. The final shot leading us to believe the entire performance was just a figment of Troye's imagination.
