Recently during the recording, IU said, "During the new year break, as I was watching 'Take Care of My Dad', I started thinking back about my relationship with my own dad, and when I received the request to sing the theme song, I was happy to take part in this. As I thought about my dad, I was able to immerse myself during the recording."

최근 녹음에 참여한 아이유는 “지난 설 연휴 '아빠를 부탁해'를 보면서 나도 아빠와의 관계를 되돌아보게 되어, 주제곡 제안이 왔을 때 기쁜 마음으로 참여하게 되었다”며 “우리 아빠를 생각하며 녹음에 임했다”고 소감을 전했다
