"I know love" is a high-energy collaboration between pop sensation Tate McRae and The Kid LAROI, featured on the deluxe edition of SO CLOSE TO WHAT???. The song perfectly captures the adrenaline rush of a relationship that evolves rapidly from platonic friendship to intense romance. With a driving beat and conversational lyrics, the track explores the blurring lines between "just friends" and lovers, using vivid imagery of travel, intimacy, and the realization that some connections are impossible to ignore.
The central metaphor of the song compares love to a drug. The feeling "hits" them suddenly and intensely, leaving them feeling "sick in the morning" and "down on their knees," illustrating a love that is consuming and perhaps a bit dangerous.
The narrative arc follows a classic "friends to lovers" trope. Lyrics like "We started off friends, how we end up here?" highlight the surprise and confusion of finding romance with someone you previously viewed platonically.
The relationship moves quickly ("now we're twelve months in"), fueled by a jet-setting lifestyle ("out in Mexico"). The song reflects the chaos of modern dating where connections can deepen rapidly amidst a busy life.
