The song title is "ä fragile heart" by westlife !

A fragile heart was broken before
I don't think it could endure another pain
But there's a voice from deep inside of you
That's calling out to make you realize

That this new bond gives inspiration
To all who feel no love appeal no more
So how can I break this wall around you
That's aiding both our hearts to grow in pain

So forget your past and we can dream tomorrow
Save our hearts for care and lovin' too
It's hard, I know, but oh one thing's for sure
Don't go and break this fragile heart.

A hurting mind in need of emotion
I don't think It's could endure another pain
But baby in you, I've found affection
Affection I have never felt before

So don't let your past destroy what comes tomorrow
Don't go and break my fragile heart

With all this fire that burns between us
There's so much to lose
Yet so much more to gain
And if I could, choose the world around me
The world I'd choose would all revolve around you
So help me complete the game inside me
And help me to mend ,to mend this fragile heart
