It's a love story, and Taylor Swift is congratulating one couple in Edinburgh, Scotland for saying, "Yes."

"I love performing this entire show in sunlight because I'm pretty sure I saw someone get engaged over here," the singer said before performing "Betty" on Friday night. "You have no idea. I never get to see that, right? Because it’s, like, dark usually at night, but it's not right now so congratulations. Wow, I just saw that whole thing! Uh, man, that's amazing!"

The open-roof of Scottish Gas Murrayfield stadium and late sunset of 9:55 p.m. allowed Swift to perform the bulk of the Eras Tour in sunlight and twilight. The arena grew dark around her acoustic, surprise set.

"Thanks for doing that at my concert, that’s a big moment — huge!” Swift acknowledged.

One couple on the right side of the stage -- where Swift was referencing when she saw an engagement -- did make it official an hour earlier during "Love Story" when she sang, "He knelt to the ground and pulled out a ring / And said, 'Marry me, Juliet / You'll never have to be alone.'"

A TikTok video captured the magic moment. Many of the comments congratulated the couple. Others commented on the Jason Kelce red-and-gold overalls outfit. It wasn't confirmed if this is who Swift saw.

'Love Story' proposals are global

The love story deed where couples get engaged at her three plus hour show has made it's way around the globe. At the start of the year in Tokyo, Nobuya Matsuoka popped the question to his girlfriend Alyssa Yeager.

Yeager explained why the moment was the perfect way to ask, "Taylor Swift changed my life, saved my life and was there during the best moment of my entire life."
