Roseann Sdoia was one of hundreds injured in the 2013 Boston Marathon bombing that killed three. Mike Materia was the firefighter who rushed to her aid, stayed by her side while she was transported to the hospital, and checked on her throughout her recovery after her right leg was amputated.

Now, he’s her fiancé.

The two went on their first date two months after the bombing, Fox 5 News reported. Materia proposed in December of last year.

“I asked him if I was going to die,” Sdoia told the New York Post, recalling the day they met. “And he told me that I was going to be OK, that I only had a flesh wound.”

Materia “was so kind and caring,” she said.

On Wednesday the couple participated in the Empire State Building Run-Up, the New York Times reported. The event benefited the Challenged Athletes Foundation. Sdoia, a beneficiary of Challenged Athletes Foundation herself, climbed all 1,576 steps with her prosthetic leg. Materia completed the challenge in full firefighter gear.

Sdoia and Materia are also scheduled in March to release Perfect Strangers, a book about four people whose lives were impacted by the bombing.
