I do not know what it is but I think I'm falling in love
I'll know what it is and I sure don't know how
But you filled my heart with butterflies, I'm falling in love

My doctor says I need no cure this time
That everything's alright and I am fine
But my friends don't agree, they say
I'm not the one I used to be

And it makes me wonder why I'm smiling all the time
The only thing I have inside my mind is a picture of you
And it's there no matter what I do, no matter what

I do not know what it is but I think I'm falling in love
I don't know what it is but when I close my eyes
You're the one I'm dreaming of

I don't know what it is but I'm floating in the sky
I don't know what it is and I sure don't know how
But you filled my heart with butterflies, falling in love

Seems like all my problems went away
I start to make the most of everyday
So I spend them with you
No one makes me feel the way you do

And it makes me wonder about the pain I get inside
Every time that you're not by my side, you have opened a door
I have never felt this way before and I want more

I do not know what it is but I think I'm falling in love
I don't know what it is but when I close my eyes
You're the one I'm dreaming of

I don't know what it is but I'm floating in the sky
I don't know what it is and I sure don't know how
But you filled my heart with butterflies

When we are walking, I get to hold your hand
And that making me proud, I'm screaming out loud
That I, I am a happy man
And when we're looking up on a clear blue sky
You give me a kiss, I wonder who is this lucky guy

I don't know what it is but I think I'm falling in love
You're the one I'm dreaming of

I don't know what it is but I think I'm falling in love
I don't know what it is but when I close my eyes
You're the one I'm dreaming of

I don't know what it is but I'm floating in the sky
I don't know what it is and I sure don't know how
But you filled my heart with butterflies, I'm falling in love
