Rewind the clock

Rewind the clock to the start
To the time before you broke my heart,
When everything was going great
Our first kiss
Our first date

Rewind the clock when cracks appeared
To the time you started acting weird
Our first fight
Our first tears
Our first spilt
Our first fears

Rewind the clock to the end
To the time my heart will not mend
So why did you kiss my best friend?
