Written by Dua Lipa and Chris Martin in Los Angeles, the rain in the lyrics is a reminder of the British songstress' home in London.
"I always miss home and I always miss the rain," she told Billboard
. "It's only when it rains in L.A. when I go, 'Oh, this is what London feels like and this is the part where I love it the most because I feel like there's a tiny bit of home that I get to carry with me every time that it rains."
Dua Lipa added: "The whole song is really about the sacrifice that you make spending so much time away from all your loved ones and your friends and your family to live your dream and do what you love."
