During his Music News interview, Ed said:

[Nina’s] about my ex-girlfriend [Nina Nesbitt], we dated for a year. It was written on tour with Snow Patrol in another hotel room. It was based on a sample from a Wretch 32 song called “Welcome To My World” from his third mixtape, Wretchrospective. I sampled the piano and made a song out of it.

When you’re a musician and you date someone, there’s always an in-between. Like, you put your family and your friends first, always, and then your career second. But when you date someone, they kind of fall in between the family and friends and career, and you don’t really know whether they’re more important than the career or whether they’re more important than family – so this is a song about that. You just need to find someone that’s OK with it, and I think by the time you have kids, that’s when your family comes first, and that’s where the woman comes, because she’s your family now. I think kids change everything, but up until then it’s different. My family understand I had to go away for 12 months last year, but until you find a partner who’d happy with that, you shouldn’t even bother. Well, you shouldn’t bother committing.
