A/N This is my first atempt at a songfic. After reading song of the stories about Dasey I thought this song would fit.

Disclaimer: Sadly I do not own Life With Derek or What My Heart Says by Monica.


Casey is sitting in her room trying to understand why everyone says it is wrong for her to love Derek. She gets frustrated and turn on the radio to try and stop thinking about it.

La, la, la, la, la
La, la, la, la

So let them say its wrong
For me to love you
They could never feel
The way that I do when we kiss
When we're close like this

"Just great, a song that fits what I feel." Casey says. She turns the radio up and began to sing the song.

They can't see inside my soul
They can't know the love we know
All they do is waste their time
They can never change my mind

Casey thought that they just don't understand. If they knew how she felt they wouldn't keep saying that it's not right. But no matter what they said she wasn't going to change her mind.

It's what my heart says
That is what I listen to
It's what my heart feels
That tells me, tells me what to do
It's what my heart knows
That's the only, the only truth I know is real
All I hear is what my heart says to me

She refused to listen to anyone. She was letting her heart guide her. Casey was so into her thought and the song that she didn't see or hear him come in. He stood there watching her, he smiled.

La, la, la, la, la
La, la, la, la
What my heart says

Let them say that I'm a fool
To fall so deeply
Cause they will never ever be
Loved so completely
How can they even talk that way?

They can't see it through my eyes
They can't feel this love inside
All their words don't mean a thing
They can't change the way I feel, no, no

Derek was watching the girl he loved. He couldn't understand why everyone was against them loving each other. Other than the fact that her mom is married to his dad. They say you can't love your step-sister. But that's not true.

It's what my heart says
That is what I listen to
It's what my heart feels
That tells me, tells me what to do
It's what my heart knows
That's the only, the only truth I know is real
All I hear is what my heart says to me

Casey turned around and saw Derek she smiled. She continued to sing the song. Derek walked over to her and they began to dance to the song. They can't help the fact that their parents decided to get married. It's not fair.

And I have never felt so sure about anything
See you are the one, the one that I need
It doesn't matter what they think
Or what they say
I'm loving you anyway, oh
All I know is what I hear

They both agreed that no matter what other people said they would love each other. You can't help who you love and they weren't going to fight their feelings.

It's what my heart says
That is what I listen to
It's what my heart feels
That tells me, tells me what to do
It's what my heart knows
That's the only, the only truth I know is real
All I hear is what my heart says to me

La, la, la, la, la
What my heart says
Oh, what my heart says

Casey and Derek were very much in love with each other. They only wished that everyone could see or feel what they feel for each other and maybe they wouldn't think it was wrong.

George and Nora were listening to Casey sing. They both agreed that they weren't going to stand in the way of true love.
