"We were friends from when we first met, and we'd hang out during free time in between filming. But I had no idea Kaitlyn liked me," he admitted, adding that the other contestants played Cupid.
"I was completely oblivious to Kaitlyn's flirtations. The other contestants had a lot to do with us getting together."
Miller added that it took a few dates for them to admit their romantic feelings.
"We went out on a few dates but it was still kind of as friends," he explained to the website.
"Then we went and had breakfast one day, and I kind of just leaned over the table and said, 'Kaitlyn, I've just gotta get something out the way. I just want to make sure... Is this... Is this a date?'
"'And she kind of said, 'I don't know. Is it?' and I said, 'I guess it is now?!'"
And the rest, is history!
