I'm Not That Girl (Reprise) is sung by Glinda after Fiyero runs off with Elphaba. She knows that Fiyero will never love her and that their relationship was never meant to last. This last part is of the love triangle with Elphaba getting the man leaving Glinda with no one when the love triangle started with Glinda with the man with Elphaba also liking the man. Elphaba and Fiyero can be seen in behind Glinda before As Long As You're Mine.
In the German production, the song is called Ich bin es nicht (Reprise), which translates to It's not Me reprise. In the Japanese production, this song is watashi janai ~ RIPURAIZU. In the Dutch Production, the song is called Ik Ben Het Niet (Reprise), which translates to I Am Not (Reprise).
It is one of the few songs where the lyrics remain exactly the same in film version as that of the original musical, though its length on the film's soundtrack is rather longer due an extended instrumental segment.

GLINDA:
Don't wish, don't start.
Wishing only wounds the heart.
There's a girl I know.
He loves her so,
I'm not, that girl...
