J?

So you guys wanted to know what his name was?
This might be uneasy... but okay

What's their name Merc?
Who's this guy Merc?
Is he light skin?
I know who it is

It's not a secret anymore
The truth is out
I gotta let it all out
So you guys know now

It starts with a J
Don't think too fast
There are many people out there
You'll just never get who

We can play this game all day
If y'all would like it
I could do this too
Just let me describe it

Black hair with the glasses oh yeah please
This person has me weak on the knees
Their everything that I wanted
Last time I left the last one haunted

You're getting closer, yeah it's true
I know it, you know it, me and you
Take your best guess I'm ready
I'll try not to freak, I'm slow and steady

So many letters to chose from
But there is one in particular
Let's see, you're close but stung like a bee
But it feels like that's the one for me

Come on you guys
You're almost there!
And I'm almost ready
To share!

You're onto me
And I'm onto you
If you figure out
That's great for you!

Goes to class with me
The hallway where I see
Walk by with a look on my face
Trying not to let my heart have a fast pace

You want the truth?
Let me get it for you
If you really knew me
Then by now it is true

Your face Is gonna drop
Look at me? Sure why not
Here's the letter
Really? Did I stutter

His name starts with J
Name starts with a J
La La La La La La La La La

You all know now
Shocked like wow
The moment of truth is here
I can't even disappear

Wonder what you have to say now
Tell me, I'm ready
Paper, pencil, anything
Let's see what you got now
