I think this is a very cute idea, having Yugi do a poem about him and Yami.

Like brothers

We are like brothers, you and I

We are always together, rain or shine

We can always count on each other

For the strength the other needs

I remember the first time I met you

I was rather quite shocked

To see a face that looked a lot like me

But, at the same time, is so different

On that day, my life changed forever

Thanks to you, I gained new friends and confidence

We are like brothers, you and I

We are always together, rain or shine

We can always count on each other

For the strength the other needs

We always help us in our tough spots

You help me rescue family and friends

From the deadly shadows around

I help you with your lost memory

We'd do anything for the other

We are like brothers, you and I

We are always together, rain or shine

We can always count on each other

For the strength the other needs

Then again, there are times

When we fight and get annoyed with each other

When those times happen

And we don't talk for a while

We remember…

We are like brothers, you and I

We are always together, rain or shine

We can always count on each other

For the strength the other needs

We will never be apart

No matter what life throws at us

Even if you leave, my brother

Even if you go back to where you belong

And never return

Always remember this;

We are like brothers, you and I

We are always together, rain or shine

We can always count on each other

For the strength the other needs

Nothing will ever change that
