Never did I thought
That I would find you
And also find my heart in you.
You make me feel something I didn't knew;
A feeling that I've only felt in you.
It's a feeling that I cannot hide
Though how hard I try to resist and fight.
It is something I must show,
Something you must know
And something I must confess...
I LOVE YOU. You are my Heart.
