Cabello told Genius
about the experience that motivated her to write the song.
"I had a friend and we were so close," she said. "Then it was like literally a day after we didn't even know each other anymore. It was weird. Anyway, I was writing it in a hotel bathroom and I wrote it over this voice memo chord progression that I had in my head. It just sounded too, not what it felt like. It felt like what the songs sounds like now. Before I was like, 'How did we let it all get this far, I don't even know who you are.' I saw the person I initially wrote it about at this thing. I just went into the bathroom. It was like a movie. I was just crying."
