Lyrics:

If you want my heart
You have to promise not to tear it apart
'Cause my heart
Has been hurt a lot
And it always seems
Love is not sweet like in dreams
Somethin' falls through
But I don't want that to happen to me and you

So be
Careful, warning, fragile heart
So be
Careful, warning, fragile heart

Last Saturday
We ate dinner at you parents place
Last Saturday you said, 'How you feel will not go away'
Well, all the fishes in the sea
They could not be happier than me

So be (Ah)
Careful, warning, fragile heart
So be (Ah)
Careful, warning, fragile heart

Only fools believe that
Nothing changes, nothing leaves
But I need to believe that we at least will have some dignity, yeah
'Cause everything changes, nothing stays the same
But that's no excuse to be casual or to place the blame
You have to be careful with me

(Ah-ah-ah)
(Ah-ah-ah, ah-ah-ah-ah)

So be (So be, ah)
Careful, warning, fragile heart
So be (So be, ah)
Careful (Careful), warning, fragile heart
So be (Won't you be? Ah)
Careful (Careful), warning (Warning)
Fragile, fragile heart (Fragile heart)
So be (Won't you be?)
Careful, warning, fragile heart
