It also reminds me of Tifa and Cloud to a certain extent in Advent Children, but the overall message of the song and especially the chorus is pure Cleris. Don't mind the footage, finding a decent video of the artist themselves singing it was difficult.

Cute song. I thought it was really good and it does remind me of Clerith.

Listening again, it was a really scratching recording. But yeah, Cleris, and Tifa in AC to an extent, Cloud just keeps trying and the both of them try and help him as best they can.
