Scenario: SHu needs to prove he's been 'Friends' With Lui. He tries to get people to help, the only person available is Rantaro (for reasons~). So Rantaro helps make fake Emails.  

This is what happens~

[Lui:]
Dear Shu Kurenai
We've been way too out of touch
Things have been crazy
And it sucks that we don't talk that much
But I should tell you that I think of you each night
I rub my nipples and start moaning with delight

[Shu:]
Why would you write that?

[Rantaro:]
I'm just trying to tell the truth.

[Shu:]
This needs to be perfect. These emails have to prove that we were actually friends. Just..I'll do it.

[Lui:]
I've gotta tell you, life without you has been hard

[Rantaro:]
Hard?

[Lui:]
Has been bad

[Rantaro:]
Bad?

[Lui:]
Has been rough

[Rantaro:]
Kinky!

[Lui:]
And I miss talking about life and other stuff

[Rantaro:]
Very specific.

[Shu:]
Shut up!

[Lui:]
I like my parents

[Rantaro:]
Who says that?

[Lui:]
I love my parents
But each day's another fight
If I stop smoking drugs
Then everything might be alright

[Rantaro:]
Smoking drugs?

[Shu:]
Just fix it!

[Lui:]
If I stop smoking crack

[Shu:]
Crack?!

[Lui:]
If I stop smoking pot
Then everything might be alright
I'll take your advice
I'll try to be more nice
I'll turn it around
Wait and see

'Cause all that it takes is a little reinvention
It's easy to change if you give it your attention
All you gotta do is just believe you can be who you want to be
Sincerely, Me

[Rantaro:]
Are we done yet?

[Shu:]
Well I can't just give them one email. I want to show that I was, like, a good friend, you know?

[Rantaro:]
Oh my god.

[Shu:]
Dear Lui Shiragajio,
Yes, I also miss our talks
Stop doing drugs
Just try to take deep breaths and go on walks

[Rantaro:]
No.

[Shu:]
I'm sending pictures of the most amazing Beyblades

[Rantaro:]
No!

[Shu:]
You'll be obsessed with all my Blading expertise

[Rantaro:]
Absolutely not.

[Shu:]
Dude, I'm proud of you
Just keep pushing through
You're turning around
I can see

[Lui:]
Just wait and see!

[Shu & Lui:]
'Cause all that it takes is a little reinvention
It's easy to change if you give it your attention
All you gotta do is just believe you can be who you want to be
Sincerely, Me

[Lui:]
My sister's hot

[Shu]
What the hell!

[Rantaro:] {Blushing} 
My bad.

[Lui]
Dear Shu Kurenai,
Thanks for every note you send

[Shu:]
Dear Lui Shiragajio,
I'm just glad to be your friend

[Shu & Lui:]
Our friendship goes beyond
Your average kind of bond

[Shu:]
But not because we're gay

[Lui:]
No, not because we're gay

[Shu & Lui:]
We're close, but not that way
The only man that I love is my dad

[Lui:]
Well anyway!

[Shu: :]
You're getting better every day

[Lui:]
I'm getting better every day

[Shu & Lui:]
We're getting better every day

[ALL:]
Hey hey hey hey!

'Cause all that it takes is a little reinvention
It's easy to change if you give it your attention
All you gotta do is just believe you can be who you want to be
Sincerely

Miss you dearly

Sincerely, Me
Sincerely, Me
Sincerely, Me
Sincerely, Me
