The staff said, "Samantha and Anais both grew up overseas, and we wanted to find a narrator who could also express their optimistic, bright personalities. Tiffany is from overseas, is always optimistic, and also is around their age, so we thought she should be perfect." Tiffany worried that her pronunciation wouldn't be good enough for the documentary, but decided to take the offer because it was something she had always wanted to try. 

She said, "When I first got the script, I was touched by their miraculous story. But after watching their video while dubbing, I was surprised and touched even more. My heart warmed seeing the two meet each other and support each other through the sadness and pain of adoption, and I was able to feel their positive energy from their bright personalities. I sincerely congratulate their miraculous meeting. I was worried about not doing well because it's my first time narrating, but I'm glad it ended well. I'm glad I was able to share this touching story to fans."
