"First impressions were really good," Kristine said. "And first kiss -- or two or three -- was pretty great!"
The 28-year-old real estate agent added, "I just feel like I'm happy that I took such a big risk."
But going into the extreme seven-week experiment, Kristine acknowledged she was "petrified."
"I didn't know what I was going to find at the end of it all," she confessed.
While it remains to be seen whether Kristine and Keith, 29, chose to stay together or get a divorce on "Decision Day," Kristine is leading Married at First Sight fans to believe they are still together and happy.
"It's still -- even to this day -- I'm still speechless about it all," Kristine gushed. "I don't really know how to put it into words. It was just -- everything about it was amazing. It turned out way better than I ever could have expected."
Jamie then asked Married at First Sight expert, Pastor Calvin Roberson, whether he had breathed "a sigh of relief" after watching Kristine and Keith's successful wedding.
"Yes I did. I did. It's always good to see that immediate chemistry and connection, and they had it just immediately," Pastor Cal said on Unfiltered.

Kristine, however, couldn't say that all of the stars aligned upon meeting Keith on their big day.
"Was Keith your physical type? When you envisioned your groom, is he something you envisioned?" Jamie asked Kristine.
"Ugh, you know what? No," Kristine confessed. "I mean, like, he's tall and very attractive. But I thought he was going to be a little more buff, I guess, which I was looking for. And I wasn't really expecting the beard. And he's a lot hairier!"
"I shouldn't say that," Jasmine noted after Jamie burst into laughter, "but I've never dated a guy with hair all over him."
"We couldn't give you everything!" Pastor Cal said with a laugh.
"I'm sorry! I'm sorry. I wasn't expecting that, but you know, the muscles can grow!" Kristine reasoned.
