"I think I was coming off the back of a couple of big songs and definitely just so driven by my ego and just feeling like something in this feels not right," Mendes recently told Apple Music's Zane Lowe of the collaboration. "And it's always resonated with me. This song has always resonated with me and it just never found its way out. And now all of a sudden I was listening to it one day, and I just started my relationship with Justin. It just started forming properly in the last three months. And I called him and I was like, 'Look, I have this song. It's kind of going there.' We go there."
