Leaving Me. (Harry Styles)

What is the definition of forever? Because, really, no one knows what it means. Yes, you can say that you will stay with someone forever, but really, no one knows what it means. So, can Kyle or Harry figure it out? Or will they leave each other? Most often, instead of being together forever, people leave. So, a lot of the times, there is no 'forever'. Will Kyle and Harry change that? Only one thing can decide that-their hearts. What their hearts believe in.
