‘It’s not like that,’ I say. ‘It’s sex positive. It subverts the audience’s expectations. But, more than anything, it’s beautifully romantic.’ I reach across and put my hand on his heart. ‘It gets you right here.’

‘Sounds intense,’ Kellen says. I feel his heart quicken.

‘Yeah, well …’ I hesitate, withdrawing my hand. ‘Maybe you should watch it.’

‘Maybe we should watch it,’ he says. ‘It’s been a while since we had a movie night.’

‘Sure,’ I say, looking across at him with a smile.

The song rolls through its closing bars before shifting through to an eighties track. I think the DJ is deliberately pulling music from all eras. They’re obsessed with the past at this place. Oakbrook is always about looking back. Never about looking forward.

I glance back at Kellen to see that he’s shut his eyes. His head is gently bopping from side to side as he listens to the music.

I shut my eyes too and breathe in the cool night air. Kellen’s right. It is nice to take a moment of peace, away from everything. I let myself enjoy it for a minute or two. Even if we are going to have to go back round again tomorrow. Right here, right now, it almost feels like everything is back to normal.

That is until I hear the sudden sound of a crack. I open my eyes to see Kellen on his feet. But he’s not just on his feet: he’s standing on the skylight.

‘Kellen?’ I say, scrambling to stand up. ‘What are you doing?’

‘I wasn’t sure if it could hold my weight,’ he says, taking another tentative step forward. ‘But I think it can. Look, it’s fine.’

‘I heard it crack,’ I say. I can’t see anything, but I definitely heard it.

‘You worry too much,’ he says, walking along the glass. Who knows how thick it is? But it’s the only thing between him and a twenty-metre drop. I’m not the only one who’s noticed either. Some of the students below are looking up now and pointing.

‘Kellen, come off there!’ I say. ‘What happened to not interfering with prom? This is definitely interfering with prom!’

‘How is it interfering?’ he says with a laugh. ‘Zach, it’s fine, look –’ He jumps, and I feel my heart stop as he bends his knees and lands.

His eyes go wide as we both hear the distinct sound of another crack.

I expect the glass to break beneath him, but it doesn’t. It actually seems to be holding his weight. He blows out his cheeks with relief.

‘Told you,’ he says, taking another step forward just as the whole thing shatters.

‘Kellen!’ I yelp, rushing forward to try to grab him.

‘Zach!’ he calls as his hand slips through my fingers.
