ALBANY, N.Y. (NEWS10) – A 4-year-old little girl who’s battling cancer got to “marry” the man of her dreams.

The knight in shining armor who stole her heart wears hospital scrubs. He is the nurse who has cared for her in the past year.

Video of the heart melting event has gone viral and really shows how much it has all meant to the little girl at the center of it all.

Abby Sayles has been receiving life-saving treatment for Pre-B Cell Acute Lymphoblastic Leukemia at the Melodies Center for Childhood Cancers at Albany Medical Center. It was there that a bond grew between her and her nurse Matt Hickling.

So how does Abby feel about being married?

“Good,” she said. “It’s my first time being married.”

The hospital staff wasted no time after Abby popped the question.

A coworker lent Hickling a tuxedo t-shirt, staff bought a few bouquets, and they laid down an aisle of rose petals.

There wasn’t any organ music, so they improvised by humming ‘Here Comes the Bride.’

“It means the world [to me],” Abby’s mom Renee Sayles said.

“Just a great moment to share with this family and everyone and what they go through day to day and to have her remember something like this,” Hickling said. “She can look back on it when she’s older and be really just touched by it.”

Renee said Abby has had a few setbacks, but her prognosis is good. She hopes Abby will one day look back at her time at the hospital as pleasant.

Abby was also Person of the Week on ABC World News Tonight with David Muir.
