Heartbreak on a summer day

Lately I've been writing
Subject matter has been mostly us
Been solving the equations
What would be the sum that would equal us?
I know that we both been hiding
But my mistakes count for twice as much
Can't deny it
We both played our parts but I ran out of luck

Cause you broke my heart
You broke my heart on a summer day
Ripped it apart
Now all I want is a rainy day
Rainy day
Hey yey yey yey
Hey yey yey yey
Hey yey yey yey
