But Drew's disdain for KC's altered beauty, love for exxy things and past in Hollywood - oh, and his love for soft toys and Cairns - would ultimately break this couple.
Before their split, they did promise to give their marriage a shot. Here, are their final vows...
KC'S FINAL VOWS
"Who would've thought that only a couple of months ago after moving back to Australia, I'd be marrying a stranger. I'm a believer that everything happens for a reason, and maybe this experiment is the reason I came home. Walking down the aisle on our wedding day, I remember thinking, oh God, I hope he's nice. Then you turned around and I saw you smile from ear to ear and I instantly felt calm. Not to mention you have one of the most beautiful smiles I've ever seen. As we started to get to know each other, I knew we had a lot of differences but yet I always felt so connected to you. Drew, I always saw so much potential in us even when you didn't. I know you don't agree with how I've lived my life that I enjoy in my life, I can honestly say that your judgement wore me down. At one stage of the experiment, I became embarrassed about what I enjoyed. But I've come to realise that I should never be ashamed of what brings me happiness. Coming into this experiment, I asked for someone that loves all of me. But I didn't get all of that. Although I didn't like your toys, and your loud t-shirts and your judgement, I was determined to get to know you. Drew, even at times when you frustrated the crap out of me, I couldn't help to start falling for you. And I am falling for you. I have missed you during our time apart. I miss how we make each other laugh how you make me feel beautiful without any makeup. I can't walk away from a man I feel so connected to. I want to try and make this work outside of the experiment. I hope that you can accept me for all that I am and I promise to be your ride-or-die in the real world and I hope you can be mine too. The end."
DREW'S FINAL VOWS
"I came into this experiment to see if I cold find love in possibly the weirdest way imaginable. Right now, I feel like I've gotten so much more out of this than I could've ever hoped for. I did realise that I did have a lot of walls up when it came to this experiment. I now know that I've been so scared to open up my heart, to potentially be hurt again. For this I feel like I owe you an apology. KC, from the moment I turned around at our wedding, and our eyes locked, we had a very special connection I felt a wave of comfort over me from the moment we touched. You, KC, are a beautiful human being, but this experiment has been a roller coaster of emotions, which is why this decision, hand on heart, has been one of the biggest I've had to make. I'm concerned that our lives are so different, and we will struggle to make it work between Cairns and Sydney. We both have very different views on the world and how we want to live. I worry it will be next to impossible to meet in the middle. We are both strong-minded people and I don't see either of us changing anytime soon. You very quickly jump to the conclusion that you wouldn't live in Cairns, which puts a lot of added pressure on me to see Sydney, the big smoke, as a place I could live. I love my home and although I could move for love, we just aren't there yet. What I do know, is that I'm not ready to say goodbye, just yet. You are beautiful both inside and out, and I'm so glad that the experts chose you for me. KC, I care about you so much. You make me so happy, and I'm not ready to say goodbye yet."
In spite of their demise, let's go back to where it all began, and remember what they promised each other before tying the knot.
DREW'S ORIGINAL VOWS
"In life there are few promises. In love it seems there are even fewer. As we embark on this experiment together, these are the things I will promise you.
"I promise I will always give you honesty and show you respect. I promise that I will be open to you and show you not only my strengths but also my vulnerabilities.
"I will be compassionate, and always consider your feelings. This is a journey my heart is wholly invested in. So sign your life away, and your stuck with me now. Sign, sealed, delivered, I'm yours."
KC'S ORIGINAL VOWS
"I wish I could stand here and say all the amazing qualities about you, but I don't know them yet. I'm sure there are so many, and I'm excited to learn and experience them all.
"I want to start this marriage with reassurance that I got you. So I promise to always be honest and someone you can lean on. I'm not a perfect person but I strive to always be the best person I can be. I'm kind and caring and someone that loves to give. I'll keep you on your toes and always entertained.
"I'll finish by saying, some moments last a lifetime, and today potentially meeting my forever person and being surrounded by all my loved ones is something I'll remember for the rest of my life. So lets start this journey with an open heart and I truly do believe that the best is yet to come."
