I'm Not That Girl

Chapter One – The Request

"Hey, Case," Derek said, opening Casey's door – without knocking – and walking over to the computer where she sat working on her homework.

"Haven't you heard of knocking?" Casey demanded, goose bumps formed on the back of her neck as Derek placed his hand on the back of her chair.

"Yes," Derek smirked, "Of course I have heard of knocking. But just because you have heard that dogs live in dog houses doesn't mean you do."

"Derek!" Casey shouted as she wheeled around in her chair to face him, "What do you want?"

"Case, take a chill pill, okay, I was just kidding. Now I came in here because I need to talk business with you…"

"Isn't that Edwin's specialty?" Casey cocked an eyebrow.

"Well…yes but you see this concerns D-Rock and I was wondering if I could talk to you about something."

"Well…considering you barged into my bedroom without knocking and basically called me a dog…"

"Case, come on!" Derek placed his hands on the back of her chair, blocking her in, "Please? Case, I was just kidding. You aren't a dog…you are more like a…half dog half human!"

"Oh, so now you're calling me a werewolf?" Casey cocked her eyebrow again.

"No…not exactly…"

"Derek, what do you want?" Casey asked impatiently.

"Okay, well D-Rock in performing at Smelly Nelly's Friday night and they want us to play a song that isn't…well…rock-ish. They want something more slow and coffeeshop-ish. You're really good at writing stuff like that so I was wondering if you would write us a song to perform Friday. You, of course, would sing it…"

"You want me to…to write my own song?" Casey could hardly believe it.

"Yeah, it's either that or no gig and this is actually a paying gig, Case."

"Alright, I'll…I'll do it. I still can't believe you want me to write my own song!"

"Hey, I don't want you to, but it's either that or no gig. Now hurry up! Start writing! Get those creative juices flowing! And remember, Case, make it good because Kendra is coming to watch us."

"Yeah, alright. I'll start on it tonight," Casey nodded as Derek walked back to the door, "You're welcome, Derek," Casey rolled her eyes.

"Oh, yeah, um…thanks."

Not long after he left, Casey grabbed her notebook and her pen and jumped on to her bed. She still had butterflies from Derek being in her room. For some reason she always got butterflies whenever she was around him. Alright, Casey thought to herself, write a song…for Derek. And make it good because his girlfriend's going to be there. Casey paused and felt a pang in her heart, his girlfriend's going to be there.
