Adrian’s words echoed in my ears all the way home to my shed. Was it true? Did everyone have someone who made them feel this way? Light-headed and loose-limbed and like they might have forgotten their own name? Because if they did, someone should have warned me before things got as bad as they did. No matter how many songs I heard or books I read or films I watched, no one had ever quite managed to put into words how I’d felt about Patrick Parker. The whole time we were together, I melted at the thought of him even as I seized up with fear that I would somehow breathe the wrong way and ruin it all. He made the sun shine, the moon glow, I had a secret smile that was just for him and there was nothing I wouldn’t have done if he’d asked. He took my breath from the moment we met and I didn’t get it back for nine whole months.

And then it was over.

I turned the music up in my earphones as I rounded the corner of my parents’ road, trying to drown out the memories.

Sumi once told me everything in life was an equation, that everything had a value and could all be worked out with maths. With relationships, you took the length of time you were together, added how desperately in love you were, then multiplied it by the degree of pain of the ending to find out how badly it would affect you. There were other variables: the amount of time you’d been crushing on someone before you got together (add ten), how good the sex had been (multiply by a hundred), unforgiving habits or unappealing fetishes (subtract accordingly) and, eventually, divide by the amount of time since the end of the relationship. That was how long it would take you to get over someone.

It was a straightforward solution for Sumi; her friend was the happiest she’d ever been and then, in a matter of moments, became the most heartbroken human alive, meaning there was only one conclusion: my ex was evil. But for me, it was more complicated. I needed more than just maths to figure out Patrick and me. Maybe one of those fancy calculators they’d made us buy in Year Eight but literally never showed us how to use. Was this what the ‘sine’ button was for?

All that was left now was a bittersweet aching, tender at the heart but warm around the edges. It was the kind of pain that felt good to press on from time to time. When I looked at my phone I was anxious and excited and sad and scared but also, there was no point lying to myself, incredibly turned on.
