From previous thread - screenshot as can't quote:
Joji: Glimpse of Us - the meaning of the lyrics
Glimpse of Us is a dark love song where Joji compares his current relationship to the previous one and the love he felt for his ex; Joji is not able to forget the love and the feeling he had in his last relationship so he tries to relive those feelings (that āGlimpse of usā) with his current partner. Without success, unfortunately.
Joji is perfectly aware that the girl heās with right now is a great person. In the first lines of the song he refers to his current partner, saying that sheās perfect, sheās able to turn rain into a rainbow. Nevertheless, he wonders why he still thinks about his ex.
In a sort of internal confession to his previous love, he asks her how that is possible. Heās with a perfect girl right now, but inexplicably he doesnāt feel it works right. The chorus therefore represents a tough confession: when he looks in the eyes of the woman heās with right now, heās actually looking for a glimpse of what he experienced with his previous partner. From here the title of the song, āGlimpse of Usā, and the true meaning of Joji lyrics.
There ya go!!!! Another wholly inappropriate song to have associated with their wedding!
