His mate: Slenderman X OC! reader

4

You were at the cafeteria with Callie.

Cal: "Hey, are you listening?"

"Oh, huh sure."

You were thinking about Slender. You really wanted to see him after the letter he left you wanted to talk. You literally know ZERO about the guy!

You wanted to hang out with him and talk things out.

Cal: "Ok, what's going on?"

"*sigh* Nothing. I just *sigh* nothing."

She looks at me and rubs my back.

"Hey, you can tell me anything."

"*sigh* So, there's this guy."

"Ok."

"We've only met like 3 times and I know NOTHING about him."

"WHAT?!"

"Shh!"

"What do you mean met 3 times but know nothing?"

"The meetings were short."

"Ok."

"Now, I like him, but again I know nothing."

"Call him or see him again to talk with him."

"Thanks, Callie."

You hug her and leave.

You were in the same forest where you met Slender you were walking when someone called out for you.

"Sis?"

You turn and see your brother.

"Jellal."

"What are you doing here?"

'Um, for a walk. It calms me down."

You lie he grabs your arm and drags you out. You start hearing bushes move.

"Sis, look leave."

"What? Why?"

"Jellal. Esmerelda."

You both turn around and you see Slender! WAIT! Did he say Jellal?!

"WAIT A FUCKING MINUTE?! HOW DO YOU KNOW MY SISTER?!"

''S-Sis?!"

"Yes, MY LITTLE SIS!"

You and Slender look at one another.

Slender p.o.v

"WAIT A FUCKING MINUTE?! HOW DO YOU KNOW MY SISTER?!"

''S-Sis?!"

"Yes, MY LITTLE SIS!"

I and her look at one another and I turn to Jellal. She was his sister.

"Um, Jellal look-"

"NO! Slender how do you know my sister?"

I look at her and at her thigh, Jellal notices this and looks at my mark. He turns to me and back at her.

"You marked her."

"Big bro-"

"YOU FUCKING MARKED HER!"

He glares at me and she holds him back.

"Jellal, calm down."

He looks at her and he looks back at me and leaves. I go to her and hug her.
