Harris told Krejci that he has found a place to stay where he is "safe and sound."

CNN affiliate KCTV caught up with Harris and asked him how he felt about all the attention he's attracted since returning the ring.

"I like it, but I don't think I deserve it," he said.

"What I actually feel like is, 'what has the world come to when a person who returns something that doesn't belong to him and all this happens?'" Harris said.

But for her part, Darling said she is just grateful for what he did. Many others, she said, would have kept the ring, or sold it.

"I really just hope that my kind of flightiness in that moment leads to something really good for him," she said.
