A woman in the U.K. has identified the mystery couple whose engagement she photographed during a stroll with her family last week.

Charlene-Louise Johnstone first shared the photo to Facebook on Jan. 18, telling her followers that she spotted the then-unidentified couple at Cleave Hill in Gloucestershire earlier that day.

“Didn't fancy running up to them and giving them the photo and intruding in their moment… so if anyone wants to help share see if we can find them as I'm sure they'd like the photo,” Johnstone wrote in the post, which soon went viral with over 17,000 shares to date.

"They were hugging and were emotional. She was wiping away tears and I’m pretty sure it was a ‘yes,’" she added, per SWNS.

Johnstone’s story also brings to mind a similar search effort that was launched in October 2018, after a photographer captured a stunning engagement on a far-off peak at Yosemite and enlisted the Internet’s help in identifying the couple.
