Brother's Best Friend

Invincible

**MGK's P.O.V**

I sit and wait for Rook to get here. A red jeep pulls up next to me and I recognize Rook in the drivers seat. 

"You got a new ride?" I ask as I hop in the passengers seat. 

"No it's my sisters. Oh yeah by the way she is staying with us. And do not try anything with her." Rookie responds.

I nod and turn on the radio. We pull in to our driveway and I hop out. Rook walks in the door first and I follow right after. 

"Take out?" Rookie asks.

"Only if it's Chinese." I smile and respond.

Rook picks up his phone and orders some food.

"I'll go pick it up, be right back."  Rookie says as he walks out.

I flop on the couch and flip on the TV. I hear music coming from upstairs, so I head up. The door to the guest room was shut; so I was assuming it was Rook's sister. I go to open the door until I hear her singing. I put my ear against the door to hear her bleating out my song Invincible.

I smile, open her door, and join her in on the rapping. She's screams and turns off her music.

"Hey" I smirk.

"Uh...hi? I'm hoping you are MGK." She says quietly.

"Yeah. But you can call me Kells. Nice voice by the way. And great song choice." I laugh.

"Oh yeah, thanks" She giggles.

'Holy hell her giggle was adorable. And she is freaking adorable. Snap out of it Kells she's Rook's sister' I think to myself.

I sit crisscross on her bed. She looks at me questioningly and I just smile. She smiles back and continues to unpack her stuff. Which honestly wasn't that much at all. I wonder what her backstory is? I notice that she had bruising on her arms. I've tried to ask Rook about her, but he always said it was a sensitive topic. 

I hear Rook come in the front door.

"Race ya to the food." I say as I run out. She does her adorable giggle and runs after me.
