Regine velasquez:
If you love me like you tell me
Please be careful with my heart
You can take it, just don't break it
Or my world will fall apart

You are my first romance
And I'm willing to take a chance
That 'til life is through
I'd still be loving you
I will be true to you
Just a promise from you will do
From the very start please be careful with my heart.

Jose mari chan:
I love you and you know I do
There'll be no one else for me
I promise I be always true
For the world and all to see

Love has hurt, some lies softly spoken
And I have had my heart badly broken
I've been burned and I've been hurt before

So I know just how you feel
Trust my love is real for you
I'll be gentle with your heart, I'll caress it like the morning dew
I'll be right beside you forever,
I won't let our world fall apart
From the very start, I'll be careful with your heart

Regine/Jomari:
You are my first romance/And you are my last
And I'm willing to take a chance/I think on the past

Regine:
That till life is through

Both:
I'd still be loving you

Regine/Jomari:
I will be true to you
I will be true
Just a promise from you will do
Only will do
From the very start (5x)
Please be careful with...
I'll be careful with..
My heart
Your heart
