To keep from confusion, this is an au where Itachi survived the fight with Sasuke but still lost his eyesight. He moved back into the leaf village after the fourth war. There he meets and eventually marries Sakura.

Now onto the poem

Another rising sun

Another peaceful day

Another "I have to run!"

Again your hand slips away

Another padding of feet on the floor

Another lonely dawn

Another slamming of the door

Then I wait for you upon the lawn

I've heard every sound

Have made so much time waste

In our home upon the ground

That you have left in such a haste

No longer do I have to fight

No exchanges of fists

For I've lost my eyesight

But I won't throw a fit

Though I had barely seen you

Perhaps just once in my life

I remember the hue

The pink hair of Sakura, my wife

You're like the sweet aroma of flowers

As corny as that seems

If I could I would hold you close for hours

For that's how I see

The nip from your lips tell me you're sweet

Your hand that I've held told me your strength

You're exactly the girl I always hoped I'd meet

And I'd go to any length

To keep you protected

I'd give away my life

For I'd rather be dead

Than fail to save my wife

My fingers run along grass to my right

Still wet from morning dew

I smile from the memory of last night

When you told me you were due

Is it a girl or boy?

What name will it have?

Oh we were so filled with joy!

Our wishes granted at last!

But will our child like me?

I'm worried they'll be frustrated

For since I cannot see

Other children's teases may make our child hated

I know you'll teach our child many lessons

You'll be the sole provider to us

But I'm so sorry Hun

That I may be useless

I want to be a good father

So I promise I'll stay

I promise to love you and my son or daughter

Until my very last day
