(In the game she is actually torn between two men in the Mara quest but in this i decided NO... she is in love with El Dragonborn)
~edited the song a little so it fit a lil~

The Dragonborn comes over the hill towards Ivarsted from the south by Fellstar Farm where Fastred and her parents are farming. Fastred had seen the Dragonborn earlier that day passing her farm, their eyes had met as he walked alone. He was heading back to White Run. She could not stop thinking about him..

Fastred:
I saw him once
Then he was gone
We were like dreamers at night
Who meet as in a trace, then part again!
Two phantoms in the shadows of the moon
Can people really fall in love so soon?
He walked alone
He seemed alone like me
Could he have known
That moment was my destiny?
I had to run away,
And it was like a dream

I saw him once
The dream was true

I saw him once,
And once will do!

In my life
I have all that I want, you are loving and gentle and good
But papa, dear mama,
in their eyes I am just like a child who is lost in a wood

(Her father pauses feeding the chickens and looks to Fastred who is daydreaming with her elbows on the fence of the farm)

Jorthor
No more words
No more words, lets drop this
There are words
That are better unheard, better unsaid

The dragonborn has come to the apex of the hill and sees Fastred on the fence, his heart begins to beat as he comes to see her, the amulet of Mara wore proudly on his chest, beside him is Lydia... who too has feelings for the dragonborn. Jorthor goes inside with Boti)

The Dragonborn:
In my life
she has burst like the music of divines the light of the sun
And my life seems to have stop as if something is over and something scarcely has begun!

Lydia & Dragonborn:
In my life,
There is someone who touches my life

Dragonborn (he tells Lydia to wait while he approaches Fastred)
Waiting near

Lydia:
Waiting here!

The Dragonborn (approaching the fence standing on the other side in front of Fastred):
A heart full of love
A heart full of song
I`m doing everything all wrong
Oh Mara, for shame
I do not even know her name
Dear mademoiselle
I am lost, in your spell!

Fastred:
A heart full of love

Fastred & The Dragonborn (their hands clasp on the fence ~all romantic like)
A heart full of you!

The Dragonborn
The words are foolish
But they're true!

The Dragonborn
Oh, were we dreaming when we met?

Fastred
Who can say?

The Dragonborn:
Who can tell?

Fastred
A heart full of love...

Lydia (interjecting from where she waits):
He was never mine to lose

Lydia and Fastred:
A heart full of you... Why regret what could not be?

Dragonborn
I saw you waiting then I knew.

Lydia:
...These are words he'll never say

Fastred:

Waiting for you!

Lydia:
...Not to me...

The Dragonborn
At your feet .

Lydia..
Not to me...

Fastred:
At your heart

Lydia:
...Not for me...

Fastred & Dragonborn
And it isn't a dream ..

Lydia:
His heart full of love

Fastred & Dragonborn
Not a dream

Lydia:
...He will never

Fastred & Dragonborn
After all!

Lydia:
...Feel this way...
