I was just a robot that was made by a smart and lonely scientist
The result could only be called a "Miracle"
There was still something lacking in me
Something that can't be made easily
My creator said it was a "Heart"
A special program

​

Days turn to months, years have passed me by
I'm all alone, with no one by my side

All that is left is just to decide on a wish
I want to know who that person was
And why he did everything for me
Toiling away working hard to make 
Me a "Heart"

​

Now a miracle begins for me
Working with incredible speed
Why do my tears seem to fall
So endlessly...

​

And now why am I trembling like this ?
I can feel my "Heart" beating fast
Is this what he made for me ? My very own "Heart" and soul

​

Mysteries, in my heart, in my heart, mysteries
Now I can finally see what happiness means to me
Mysteries, in my heart, in my heart, mysteries
Now I can finally feel all of the sadness in me
Mysteries, in my heart, in my heart, again
How deep are these feelings inside of me ?

​

Now I finally see why I was born

The reason why you gave me a "Heart"

All alone, brought in this world, I'm by myself
