The upbeat and anthemic track will feature as the flip side to One D's next single, 'One Thing'.

Check out the preview above and take a look at the lyrics beneath us.

Lyrics:

I keep playing inside my head, all that you said to me
I lie awake just to convince myself this wasn't just a dream
'Cause you were right here and I should have taken the chance
But I got so scared and I lost the moment again

It's all that I can think about, oh, you're all that I can think about

Is your heart taken? Is there somebody else on your mind?
I'm so sorry, I'm so confused
Just tell me, am I out of time?

Is your heart broken? How do you feel about me now?
I can't believe I let you walk away when
When I should have kissed you

I should, I should oh, I should have kissed you (x4)
