Matthew is your ex.He is actually a singer and guitarist in a band.He was too busy with his band, to the point that he almost forgot about you.He doesn't have time for you, so you decide to break up with him.no one knows the relationship between the two of you, because you two are dating backstreet

5 years have passed, Matthew's band is increasingly famous, and Matthew is the most famous among all the members of the band which consists of 4 people.on the 30th they held a concert.three of your friends really like that band, and invite you to go to the concert.You were actually forced to come because they insisted. Even though you didn't want to see Matthew again...

You and 3 of your friends are watching the concert, you all get seats very close to the stage.your three friends are very happy, and you are just silent, you really don't like this.then while they were singing some songs, Matthew said into the microphone Matthew:"hi everybody.We will all sing a special song for all of you, because we rarely perform this song in concert.so the song is "she's not mine anymore" all the fans immediately screamed, because they were going to sing that song, it's most fans' favorite song,but you don't know this song because you are not their fan

Matthew and his band sing this song, it's a sad song but very nice to listen.Within seconds, you realize the lyrics are saying something, it's like...about your relationship with Matthew.the lyrics really describe you and Matthew.Actually, Matthew wrote all the lyrics to this song, for you.He's so into the song, that he doesn't realize you're actually watching his concert Matthew:"We used to be together, but now we're not" he sings the lyrics of the song
