Many years ago, while serving in the military, Danny Daniels signed up to be a bone marrow donor with the hope that he could help his ill friend in need of a transplant.
Unfortunately, his friend passed away before finding a match.
Years later, Daniels got an unexpected call saying he was the perfect match for a 15-year-old girl named Greta Hokanson, who had been diagnosed with Chronic myelogenous leukemia.
"How can you not give a young person a chance?" Daniels says in an interview on The Ellen Show.
Two years after undergoing the life-saving procedure, Hokanson met Daniels in person. They kept in touch through Facebook, according to Buzzfeed, and then 10 years later, Hokanson began planning her wedding.
She put Daniels and his wife at the "top of [her] list," she tells Ellen.
But she wanted to honor Daniels in an even bigger way.
So Hokanson planned a special one-on-one dance for the pair to share. The footage is enough to tug at anyone's heartstrings.
"It was such a thrill," Daniels says, describing the dance to Ellen. "I was totally honored to even have the opportunity to even get an invite to the wedding and then to be able to show up was fantastic."
Their story is a simple reminder that becoming a donor could give you the opportunity to save someone's life, too.
