In April 2013, Roseann Sdoia was being rushed to the hospital after being injured in the Boston Marathon bombing. A firefighter named Mike Materia was by her side trying to help calm her down.

Almost four years later, the two of them are getting married.

Sdoia was near the finish line at the marathon cheering on a friend when the pressure-cooker bombs that took three lives and injured hundreds went off. She was badly injured but soon Materia was there.

Charged with escorting her to the hospital, Materia rode with her in the back of a police vehicle.

"I asked him if I was going to die. And he told me that I was going to be okay, that I only had a flesh wound," Sdoia tells the New York Post.

Due to the severity of her injuries, Sdoia's right leg had to be amputated above the knee.

Materia visited a couple days later while Sdoia was recovering in intensive care and made a big impression on Sdoia's mother.

"In the hospital, my mom tried to set me up with him," Sdoia told the New York Post. "She was like, 'Oh, did you see that firefighter? He’s so cute.' And I was like, ‘Mom, I just got blown up.'"

As the weeks went by, a friendship materialized as Materia helped Sdoia track down a prosthetic and both physically and emotionally get back on her feet.

Then, a romance started to bloom. "There was an interest growing in each other, kind of quietly, until we talked about it," Sdoia told The New York Times.

The couple went on their first date in June 2013 and in December 2016, Materia proposed in Nantucket with the help of their dog, Sal.

Sal was wearing a dog tag that read, "Mike wants to know…If you’ll marry him."

"Sal means so much to both of us," Sdoia explained to the New York Post. "It couldn’t have been more romantic."

This March, the couple will release a book telling their story called Perfect Strangers. They plan on getting married in October or November.

"I do feel that, in a sense, some things happen for a reason," Sdoia said.
