PHOENIX (KSAZ) - Rachel O'Brien and Levi Conlow may be young to be engaged, but they've known each other longer than they haven't.
"We were in the same first-grade class together, but we didn't start dating until high school," O'Brien said.
That's why when Levi decided he wanted to make Rachel his wife, he knew the proposal had to be extra special.
Thanks to a sign reading "Live Marriage Proposal" with the date and time, and ending with "You and I Forever," the results were amazing.

"I hadn't seen the sign or anything so coming into it, I was totally shocked, but when it happened, I was just like stunned with happiness," O'Brien said.
Levi says, thankfully, he was cool under pressure.
"Extra thousand set of eyeballs staring at you just amplifies the nerves, but once it got down, it was just myself on my knee," he said. "It felt like we were the only two there, it was a great moment."
Levi says when it comes to the decision of spending your life with someone, no matter what age, when you know, you know.
"It's mustering up the courage to finally do it and the right timing and all that fun stuff, and she's perfect for me and that's why I proposed," he said.
