Season 21 “The Bachelor” star Nick Viall and his new fiancee, Montreal special-education teacher Vanessa Grimaldi, say they understand the artificial nature of reality-show relationships and have adjusted their expectations accordingly.

“I think every couple before us [has felt] the pressure” to live up to viewers’ expectations of a lasting relationship, Viall, 36, said in a conference call with reporters Tuesday. “That pressure exists, there’s no denying that,” the Wisconsin native said, adding, “Vanessa and I have always been realistic and this is about us focusing on our relationship and tackling that relationship outside of that world. We’re going to be realistic, do our best and treat each other with the respect we know we deserve.”

Following Monday night’s episode, in which Viall chose Grimaldi over runner-up Raven Gates, Canada’s 29-year-old Grimaldi said she’s planning on moving to the United States. “It’s something I was open to the idea of doing,” she said. “I was just waiting for the right moment to do it. And after being engaged to Nick, I knew that it was the right decision to make.” For the time being, the two will reside in Los Angeles, where Viall is rehearsing as a contestant on the next season of “Dancing With the Stars, which starts Monday.

Viall previously had been in software sales for the Chicago company SalesForce.com, which he said was “always encouraging me to take risks and always left the door open for me to come back. . . . Since then, obviously, being part of this world opened up other doors and gave me a platform” that he and some partners “four or five months ago” used to develop an online men’s grooming-products business, The Polished Gent. “We have yet to launch it publicly,” he said. “We don’t have a date yet.”
