Zoe Fern is a big Ed Sheeran fan. She's been to multiple concerts, knows every song, and can't get enough of his rumored quirky personality. So when she hears about a contest to win a lunch date with him, she enters just for the heck of it. To her surprise, she's the winner out of about a million others. But what to Ed is just some publicity stunt becomes a deep and intimate time. And soon, after spending more time together, he thinks he has extra feelings for the courageous and open girl. Just one minor setback: Zoe is seventeen, and Ed is twenty-two. They are bonding fast and must decide how to handle it: can they put aside their feelings and just be friends, maybe even just wait it out for a couple years? Or should they just insist 'age is just a number'?
