Here is one from Marik & Malik(as many have been asking for, the next one
I'm going to do is Seto/Joey or vise versa). This one is called 'hush
little baby'. I saw the episode where Malik was made a tomb keeper via
Rishid's memories and I kind of thought about it.

Hush little baby
I know you've been hurt
And alone
And feel betrayed
Hush little baby
I know how that feels
Feeling like no one loves you
No one cares about your worthless carcus
Hush little baby
But your wrong
Someone else will always cry for you
Hear your pleas and sorrows
Hush little baby
And there is someone to comfort you in your sadness
Your pain
Your regret
Hush little baby
Someone to take it away
To show you kindness
And love
Hush little baby
I, unlike you, had no one to comfort
No one to hold
No one to tell my pain to
Hush little baby
You are very lucky
That you didn't end up like me
So very lucky
Hush little baby
You have someone to comfort you
Someone to take your pain and sorrow away
Someone....that we both know
Hush little baby
Yes, we both know this person
One of us know him very well
One is still learning who he is
Hush little baby
You do know him very well
I am still learning about this person
Though it should be the other way around
Hush little baby
I should know this person better than you
But, he is so closed off
To me and tries to be to the outside world
Hush little baby
You want to know who this person is
That is so mysterious
And so closed off
Hush little baby
You know his name
I hope you know
His voice and his touch
Hush little baby
That person.....
He is....
He is me
Hush little baby
Yes, he is me
You know me
Better than I know myself
Hush little baby
I have been searching
For answers
For beliefs that I can hold
Hush little baby
So that I can find myself
In this dark and cruel world
But I have found something much better
Hush little baby
Something better than myself
Or anything else in the world
I have found you, my hikari
Hush little baby
You truly are the greatest treasure
That I have ever found
In my entire presence in this world
Hush little baby
Yes, you have been hurt
And betrayed
And violated
Hush little baby
But me
I would never betray you
I would be betraying myself if I did
Hush little baby
You are my light
In the darkness that consumes me
For ever so long
Hush little baby
You helped me through the darkness
And the pain
You made me see the light
Hush little baby
You have comforted me in my darkest hour
And now
It's my turn to help you, my little baby, Malik
