In my opinion this song is about having cheated on someone special to him. It sounds like he enjoyed it at the time in verses like this:
I like this motion
I like this heat
I like this breathing
And I know I like this beat
But afterwards he's stuck with the image of what he's done and the shame of it. you can hear his regret when he sings about tearing out his heart and in the chorus:
One stranger
One heartbeat
One love is
Forever
One picture
One morning
One tear lasts
Forever
One reason
One secret
One lie is
Forever
One nightmare
One rumour
Your shame is
Forever
