There was only one light on in the entire Weeks house, his. Kane wouldn’t be back for a while. So he was in there. Why wasn’t he checking his phone?

I watched for a little longer, willing my phone to buzz, but it didn’t.

I’d finally made the decision to go over when I saw a silhouette in the window. Just a shape, beyond the blinds.

And then another. They joined together, and my heart dropped.

I’m not sure what I was thinking when I did what I did next. I grabbed my camera, then hurried downstairs and out the door. I ran across the street to Declan’s house, climbed the trellis and peeked inside.

At first, I saw nothing, and hoped what I’d seen was all a big misunderstanding. Maybe Kane had come home early. But when I moved to the side to see between the windowsill and the closed blinds, I saw the curved slope of Luisa’s naked back, her white-blond hair tumbling down over her shoulders.

This was a mistake, I told myself, scrabbling forward on the roofing tiles, pushing ever closer to see something that would explain away what was happening inside.

Instead, the vision only got clearer. Luisa was naked, straddling him. Straddling my Declan. He had his hands around her backside, holding her on him. His top half was propped against the headboard, and he had a look on his face… It was the same look he’d given me outside the school that afternoon. Just…dead. He wasn’t happy anymore. He held her as she moved on him, wriggling, bouncing, tossing her head back. I could hear her animal noises through the closed window. But he was so, so silent.

Revenge. That was the first thought that hit me. His. Mine. I felt the weight of the camera in my hand. I don’t know why I’d been saving that last picture for our selfie. I’d take this picture and photocopy it, plaster it around school. Make them pay.

I raised the camera to the window, my eyes bleary with tears, unfocused. I snapped the picture, not caring what was in the screen as I watched him lurch forward, his hands tightening around her back as he came.

This was the boy who’d wanted to wait for marriage.

I went back to my house quietly and riffled through my jewelry box. I pulled out the tiny heart with the diamond and stared at it. Then I went in front of the mirror and put it on, trying to erase the images I’d just seen. Only two words stuck in my head as I climbed into bed, my eyes swollen from crying.

We’re forever.

Friday, March 1

I roll over in bed and am hit by bright sunlight slashing through the blinds.
