"Hmm...I think, maybe I've got an idea for the bridge, listen: I'm yes, she's no, when I hold on he just let's go. We're perfectly imperfect, but I wouldn't change a thing." I smile proudly when I offer my idea of a bridge for the song we're writing to you.

We're in the recording studio, supposed to work on songs for our next, and last, album before the band is taking a break. Louis and Liam are in the studio next doors and Niall is sick and didn't come today. We're sitting next to each other on the couch, me holding a pencil and scribbling down lyrics in my journal, you trying to create a melody on the guitar to it. And somehow, we ended up writing a duet about our relationship instead of songs for One Direction's next album. It's just so easy to work in the studio with you, not only because you have a perfect pitch, but also because you're passionate and ambitious, which is amazing to watch.

And in stark contrast to our effective way of working together stands our relationship. We've been together for about three years now and sometimes I really think it's a miracle that we haven't called it quits yet, because we're actually polar opposites. I'm extroverted, loud, carefree and outgoing, always getting in trouble with Modest for partying and drinking too much and being in the tabloids way too many times; but what should I say? I'm thriving the Rockstar-image. And then there's you; calm, level-headed, almost a bit shy sometimes, always the voice of reason — the calm in my storm. And as much as you're going on my nerves sometimes with your sensible nature, you're that one thing that keeps me grounded — and out of trouble.

The song we're currently working on is very personal, I don't know if we're ever going to release it, maybe one day. It's about our differences and how we're driving each other insane, but still manage to keep the most important thing: unconditional love. And maybe that's just it, you know? Maybe that's the whole thing; to love one another, flaws and all, truly and without conditions.

"And then we just start the last Chorus: We're like fire and rain, you can drive me insane, but I can't stay mad at you for anything. We're like Venus and Mars, like different stars, you're the harmony to every song I sing, and I wouldn't change a thing. — how does that sound, Love?"
