This Wasn't The Plan

This wasn't the plan
I can't explain this
The feeling I get
Every time we kiss
Maybe it's bliss
He makes me forget
About all the pain and regret 
We both know what this is
If I give him my heart
Well he give me his
A promise for a promise
This wasn't the plan
Should I have ran
Scared of falling again
All good things must come to an end
We just don't know when 
We both know what this is 
If I give him my heart
Will he give me his
A promise for a promise
This wasn't the plan
