How thoughtless
I had sometimes been
I hurt you so badly

But now I feel the pain
I talked to you as if
I knew just everything

Maybe I didn't lose
But I know I didn't win
How careless

I had sometimes been
I gave you the heartache
But I felt the pain

I wanted to tell you
How much I love you so
I know I'd been careless

I forgot to let you know
Sorry, I'm so sorry
I didn't mean to hurt you

You know I got hurt too
Sorry, I'm so sorry
I didn't mean to break your heart

Please let me make a brand new start
How crazy
I had sometimes been

I hurt you so badly
But now I feel the pain
Next time I'll know better

I'll have more time for you
I'll listen to your heart
Just like you asked me to

Sorry, I'm so sorry
I didn't mean to hurt you
You know I got hurt too

Sorry, I'm so sorry
Forgive my many faults
And the foolish things I've done

I was so insensitive
And I didn't understand
Sorry, I'm so sorry

I didn't mean to hurt you
You know I got hurt too
Sorry, I'm so sorry

I didn't mean to break your heart
Please let me make a brand new start
