[Verse 1: Kim Chiu]
What is this I'm feeling
I just can't explain
When you're near
I'm just not the same
I try to hide it
Try not to show it
It's crazy
How could it be?

[Chorus: Kim Chiu]
I've fallen for you
Finally my heart gave in
And I've fallen in love
I finally know how it feels

[Verse 2: Gerald Anderson]
When you said hello
I look in your eyes
Suddenly I felt good inside
Is this really happen
Or am I just dreamin'
I guess it's true
I can't believe

[Chorus: Kim Chiu & Gerald Anderson]
I've fallen for you
Finally my heart gave in
And I've fallen in love
I finally know how it feels
So this is love
[Bridge: Kim Chiu & Gerald Anderson / Both]
Doesn't matter where I am
Thoughts of you still linger in my mind
No matter what time of day
I've really really fallen for you

[Chorus: Kim Chiu & Gerald Anderson]
I've fallen for you
Finally my heart gave in
And I've fallen in love
I finally know how it feels
I've fallen for you
Finally my heart gave in
And I've fallen in love
I finally know how it feels
So this is love
