That was the break-out role for Monica Moore Smith, an up-and-coming LDS performer.
Well, her biggest role to date took place in the video linked here.
We know the story—boy (Justin) meets girl (Monica) by swiping right in a free dating app (no, not Mutual). It was six months to the day that they started dating that Justin took Monica (and Luke Porter Films) out to get some fresh air in nature—but most everyone was surprised when he got down on one knee—and mayhem (in a good way, of course) ensured!
Monica writes the full story of Justin's proposal on her blog.
