I look back at Harry and he’s pointing towards the far left corner, grinning at me. Then he starts walking towards the corner, humming ‘We’re All in This Together’, and I follow him.

“NICK, MATE!” Harry shouts over the crowds of Year 13s, all holding food and red plastic cups and taking photos of each other.

And there he is.

He turns round from a small group of people, a slightly dazed expression on his face as if he’s not quite sure whether he’s imagining Harry’s voice.

I have been going out with Nick Nelson since I was fourteen. He likes rugby and Formula 1, animals (especially dogs), the Marvel universe, the sound felt-tips make on paper, rain, drawing on shoes, Disneyland and minimalism. He also likes me.

His hair is dark blond and his eyes are brown and he is two inches taller than me, if you care about that sort of thing. I think he’s pretty hot, but that might just be my opinion.

When he spots us, he waves enthusiastically, and when we finally reach him, he looks at me and says, “All right?”

Nick’s High School Musical costume consists of a pair of bright red gym shorts and a red tank top. He’s pinned a piece of paper to the front with a very badly drawn wildcat on it. If I’m honest, he’s had worse outfits.

“You didn’t text me back, bitch,” I say.

He sips his drink. “I was way too busy getting my head in the game.”

Then he holds up a disposable camera and, before I have the chance to smile or make sure I look in any way presentable, takes a photo of me.

A second too late I hold up my hand in front of the camera. “Nick!”

He lets out a loud laugh and starts rewinding the camera before putting it in his pocket. “Another one for the Derp Charlie collection.”

“Oh my God.”

Harry’s already wandered off to talk to another group, so Nick steps a little closer and our hands automatically touch, his hands tapping mine like we’re playing a clapping game. “You sticking round here for a bit? Or are you revising?”

I glance round. “I wasn’t really revising. I was watching Mac DeMarco concerts.”

“Mac DeMarco?” Nick laughs. “I thought you said he was a dickhead.”

“He is, but his music’s good.”
