i’m still waiting for the day when Klaine sings this song.
Blaine FINALLY moving to New York to be with Kurt. Them walking down the NY city streets together for the first time, talking about their wedding, their future. Then Blaine starting to get overwhelmed with starting at NYADA and the wedding, and Kurt reassures him again that they are in it together and that everything will be okay because they love each other and nothing can change that. Then they move into this song.
It would be perfect!
