Sheeran dated Scottish singer Nina Nesbitt in 2012. During their romance, he toured with Snow Patrol for three months before embarking on his own tour for two months, causing the couple to spend a lot of time apart. In "Photograph," Sheeran details their long-distance relationship with lyrics like, "When I'm away / I will remember how you kissed me / Under the lamppost back on 6th street / Hearing you whisper through the phone, 'Wait for me to come home.'"
The singer continued to touch on being apart in his obviously titled "Nina" with lyrics like, "Oh Nina, you should go Nina / Cause I ain't ever coming home Nina / Oh won't you leave me now / And I've been livin' on the road Nina / But then again you should know Nina / Cause that's you and me both Nina / Oh won't you leave me now, now." Speaking about the songs in 2014, Nesbitt said, "He warned me it was happening but I didn't know it was going on the album. I knew there was a song. I'm not really bothered. It was quite a long time ago and it's a good song. I have written quite a few songs about Ed that are on the Peroxide album and people can probably guess which ones. I'm not going to go into detail about it but we are both songwriters, so naturally we were going to write songs about each other. It was a long time ago now and we've both moved on."
