男聲：
I'm so in love
It's just the way I feel
There's no need to hesitate
You know I'm gonna tell you everything
女聲：
Why is it so hard to say
The words that are in my head
What is it about a man
That makes him afraid to give his heart away
男聲：
Oh baby you don't have to cry
It's gonna be alright
I'm gonna make you see
You don't have to hide
女聲：
You don't have to hide your feelings
Just let them all unfold
And I will be there for you
Through every step along the way

And every moment I will hold you close
Through the happiness and the pain
No matter what comes our way
You know we'll always be in love

When you feel the world is grey
And you're feeling all alone
Just remember that I'm here
And I won't let go, I won't let go, no no no no
