In a sit-down interview with the queen herself, Oprah, Kim Kardashian revealed what makes her relationship with Kanye West work. Is it the fame? The money? The ego? The penchant for design?

Not necessarily. In a preview for her interview on ‘Oprah’s Next Chapter,’ Kimmy K. says that she thinks West’s age (a ripe 35 years old) is what makes the duo tick. “Before, all my boyfriends were younger. I always dated five years younger,” Kardashian, 31, told the Big O. “Now I just love that I’m with someone that’s a couple years older than me.”

Of course, there are other influences at play. Kardashian and West are both fashion-conscious, each having their own clothing lines. They also like to demonstrate their affection with their dollars. K-Dash gifted Yeezy with a Lambo for his birthday (worth about $750,000), while West gave Kardashian’s mom, Kris Jenner, a $200K Bentley. The couple also have a history, having been friends (and, if Amber Rose is to be believed, friends with benefits) for years.

Fans will have to tune in to see Kim’s response to Oprah’s big question: “Is Kanye West the new fairy tale?” Considering the pair have been talking about marriage and kids, the answer may be pretty clear — though they have a much more expensive alternative to glass slippers in their love story.
