"Hurts so bad, thinking of the times we had.
Can't help from feeling blue every time I think of you.
And you say you're done with me.
I was done, but now I see..."
That's from a song that Daniel wrote for his ex-fiancee, Sabrina Timms, with whom he fathered a daughter, Hope.
"We had a difference of opinions about what we wanted for the future," said Sabrina. "I wanted to settle down."
"And I wanted to follow my dreams," added Daniel.
"He wanted to do his music," she finished.
So much for what they had once hoped might be a perfect romantic match. Despite the break-up, Sabrina and Daniel remain close friends and co-parents.
Now, they're a perfect match again, but in a most unusual way.
In January 2013, doctors diagnosed Sabrina with double kidney failure. She went on dialysis and also on the list to find a suitable donor. The odds are long. Patients wait decades.
In searching for a match, doctors began with Sabrina's friends and family. Daniel took the test, too. Of all the millions of people in this world, he, her ex-fiance, turned out to be a perfect biological match.
"Daniel volunteered immediately," said Sabrina's mother, Julie Timms.
"I'm like the medicine she needs," Daniel said.
He will donate that kidney next Tuesday, and in doing so, will pay the most ironic of prices. Daniel must give up a national music tour.
"That tour was my biggest dream," he said. "In the end, though, this is more important. She is my child's mother."
It's the concept of a perfect match that has come around full-circle. Having sacrificed a relationship for his music, now Daniel is giving up that music for the very same woman's life.

Sabrina Timms needed a kidney transplant and of all the donors in the world, her ex-boyfriend Daniel Burdick turned out to be a perfect match. They broke up years ago because he wanted to pursue his music career. Then, ironically, to ease Sabrina's pain, Daniel abandoned a tour that might have changed his career.
