Chapter 1 The Date

Casey's Point of View

My name is Cassandra McDonald. I'm 17. I used to have a nice, normal, laidback life in Alberta, Canada, until my Mom turned our world upside down and moved us here…to Toronto .

Naturally I had to change schools, which meant I had to leave my friends.

Unfortunately my new school was not the dark, damp, prison atmosphere I had hoped for. No, my new school is actually a nice, new set of buildings sitting on grassy hills overlooking the town. The classrooms are all newly painted, bright, and sunny, the teachers are all really nice and helpful, and the students were very welcoming; so I couldn't beg to move back to Alberta and stay with my Aunt Fiona and go to my old school. I like my new friends and a lot of the kids are really nice, except for one.

Derek Venturi, the most irritating, infuriating, pigheaded boy I have ever met. He's also the hottest and the most popular guy in school, which also makes him arrogant.

"Casey?" A knock sounded at my bedroom door, interrupting my thoughts.

It was my little sister, Lizzie.

I sat up against my headboard. "Hey what's up?"

"I need a favor from you, there's this boy..." Lizzie sat down on the edge of my bed.

"So who is this boy?" I asked excitedly, ignoring the favor part.

Lizzie sighed. "I'm getting to that. His name is Edwin"

"And?" I waited expectantly.

"Well I wanted him to come over this afternoon but…" She fell silent.

"What is it Liz?" I asked a little impatiently.

Lizzie lay back on my bed. "Edwin isn't allowed to come over unless his older brother brings him."

"So what's the problem?"

"Well we want to go to the mall and hang out, but Edwin's parents said that his brother has to go with us. Edwin told me just now that his brother wasn't going unless there was a' hot' girl involved." Lizzie took a deep breath and smiled innocently at me. "And that's where you come in."

"Liz-" I started.

"It's just for one afternoon. Plus Edwin already told his brother about you and his brother agreed to come. Please Casey? I really like this guy."

I looked at her. "Liz I don't know…"

"Please, please, please?" Lizzie sat up and gave me her famous 'little lost puppy dog' look.

"Okay fine, but this is the ONLY time I'm going to do something like this!"

"Thanks Casey! You're the best!" Lizzie jumped up and gave me a hug.

"Aw, you're welcome, but you owe me big time!" I hugged her back.

"I know." Lizzie went to the door. "They'll be here in 20 minutes."

"Lizzie!" She ducked as a pillow came hurtling towards her.

"Bye!" She ran down the hallway.

20 minutes later the doorbell rang and I heard Lizzie run down the stairs.

I still couldn't believe that I was about to go out with a boy that wouldn't help his kid brother out unless there was a girl involved. "That sounds like something Derek would do." I stopped brushing my long brown hair. "It couldn't be him, could it?" I thought out loud. "Nah, there's like 200 boys in my school, that's like 1 in 200 chances that Derek is Edwin's older brother!" I assured myself.

I grabbed some pink lip-gloss and swabbed it on.

"Casey!" Lizzie yelled from downstairs.

"I'm coming!" I took a deep breath and started down the stairs.

When I reached the bottom of the steps, nobody was there. "Lizzie? Where are you?"

I turned to go into the living room and collided with someone that was coming out.

I looked up to see an obviously toned, muscled chest encased in a brown t-shirt. My gaze traveled further upward to the guy's face.

"AHHHHHHHHHHHH!" I screamed so loud people in the next town probably heard me.

"Surprised?" Derek Venturi asked sarcastically.

"What are you doing here?"

"I'm here to hang out with my little brother's girlfriend's older sister. I must say when I found out it was you I almost didn't come, but then I thought- why not have a little fun at Casey's expense?" He crossed his arms and gave me that little half grin that all the ridiculous girls at our school swoon over.

I glared at him. "Well I didn't know it was you, if I had, I wouldn't have agreed to go."

He laughed. "Casey, Casey, Casey. Let's not be immature about this. We should make this an enjoyable experience for our siblings. Our mutual hate for each other shouldn't get in the way of this."

"For once I agree with you. So you're going to keep all of your sarcastic and rude comments to yourself." I told him.

"And you're going to keep your bossy mouth shut or I'll shut it for you." Derek sauntered back into the living room.

My mouth dropped open. "He wouldn't dare." My eyes narrowed and I started to go after him.

"Casey?"

I turned around to meet Lizzie's questioning gaze. "Are you okay?" she asked, concern mirrored in her brown eyes.

"Yeah. Ready to go?" I put on my most convincing smile and grabbed my purse and keys.

"We're going to ride in Derek's car." Lizzie told me as a cute, dark haired boy that could only be Edwin walked up behind her.

"Alright." I smiled brightly, probably a little too brightly considering the strange look I got from Lizzie. "Are you sure you don't want to take separate cars?"

"Yeah, Derek's car is awesome!" Lizzie grinned.

I frowned as I followed them out the door. This should prove interesting.

Derek's car was a small black sports car, and when I say small, I mean small. It makes me wonder how a boy with an ego as big as his can even fit into it.

Somehow I ended up seated in the front next to him, with Lizzie and Edwin in the back. I had tried to sit with Liz but they all insisted that I have the better seat up front. If you ask me I would rather be stuck back there with a lovesick tweenage couple then have to sit up here with Derek. So I spent the whole car ride stewing over that and trying to subtly slide my body as far away from Derek as possible.

When we got to the mall Lizzie and Edwin immediately left us to go see a movie. My sister definitely owes me.

"I'm going to Starbucks." I told Derek, as if I need to ask his permission.

I started to walk away.

"What? You're just going to walk off and leave your date?" Derek asked.

"You are not my date. I only agreed to do this to help my little sister." I shook my head and continued to walk away.

Derek laughed. "Okay if that's the way you want to see it."

I rolled my eyes and kept walking.

"I'm coming too." Derek caught up with me.

I sighed. "Why are you doing this? Do you enjoy making people's lives miserable?"

"This has nothing to do with you; I just want an iced coffee. Besides I don't make everyone miserable- just you." He pointed out.

I shook my head and stalked into the Starbucks.

Derek's POV

I watched her stalk away from me and chuckled. Casey MacDonald, how do I describe such a complex person?

She's a very smart, talented, unbelievably gorgeous girl. Unfortunately she's also an intense, know-it-all, control freak who absolutely drives me insane.

Even now she's turning to give me this look like 'you're such an idiot'. Which I realize is probably true considering I am standing in the doorway of the Starbucks just staring at her like a moron. I quickly walked into the café.

It looks like her and the guy at the counter have something going on.

I walked up behind her and put my arms around her waist. "Hey baby, what are you getting?"

The guy immediately backed off.

"Derek! What the heck do you think you're doing?" Casey turned around furiously.

"Nothing." I smiled as I looked down at her. She's so mad she doesn't realize that my arms are still around her.

"Get your filthy hands off of me!" She growled.

Okay…maybe not. I released her. She grabbed her latte and went to a small table in the corner.

After I got my iced coffee I went and sat down at the table with Casey.

"Go away Derek." She turned away from me.

"Nope." I leaned back in my chair and relaxed.

"There was nothing said about us having to stay with each other. So why don't you go find one of your bimbo fans to hang out with? There are plenty of them here. This is a mall!" She exclaimed.

"Because I don't want to hang out with someone else. And now I've got to keep an eye on the Starbucks goof who keeps checking you out!" I raised my voice on that last part so he could hear me.

Apparently I was successful because he went into the back room.

"Would you quit making it look like we're a couple? We're not!" Casey whispered loudly.

"I never mentioned us being a couple. Are you sure you didn't just dream that?" I smiled at her.

Casey stood up angrily. "I cannot believe you! Do you honestly think that I want you as a boyfriend? If you do, then you're delusional." She shook her head and laughed. "Your head is so big I'm surprised the necks of your shirts aren't stretched."

I looked up at her and gave her my most maddening smirk. "You like me, you know you do. You've liked me ever since you first laid eyes on me, you're just too afraid to say it. So you act like you hate me."

Casey's bright blue eyes widened and she just looked at me. "Maybe you're right."

I looked at her in amazement. "What?"

"I think you're right. Maybe I act this way because I like you." Casey nodded. Her eyes softened as she came over and stood next to me.

I shook my head in shock. "You're kidding right?"

She put her face down next to mine, and her breath tickled my ear. "I'll just have to test this little theory out." She whispered. She put her small, warm hand on my face and turned it towards her. I closed my eyes prepared for a kiss. I received a stinging slap across the face instead. My eyes flew open.

"Don't flatter yourself Derek, I do hate you." She threw her empty coffee cup at me and left.
Casey's Point of View

I walked out smiling with the satisfaction that I had gotten Derek good. He had actually thought that I was going to kiss him. What an idiot.

Throwing my coffee cup at him had added a nice touch. I smiled and walked towards the movie theater.

Derek's POV

I watched her walk out in stunned surprise. She had thrown her coffee cup at me. Unbelievable.

"She's a drama queen." I explained to the dozen or so people giving me the evil eye.

I got up and threw both coffee cups away. Then giving the Starbucks one last look turned and walked out. I saw the movie theater on the other side of the mall and walked towards it, sitting down on a bench to wait for Lizzie and Edwin. No telling where Casey went.

It was funny though; I actually held some respect for Casey now. She really had me going for a minute there.

I leaned back and closed my eyes. Wow this bench is really uncomfortable. I dozed off.

Someone tapped me on the shoulder. I opened my eyes to see Casey standing there looking at me. "Were you seriously thinking of falling asleep on that bench?" she asked incredulously.

I glared at her. "Well I was asleep until you rudely punched me in the shoulder."

"I didn't punch you, I poked you." Casey sat down next to me.

"You so punched me." I argued.

"I did not…" Casey protested. Then she smiled wickedly and punched me in the shoulder.

"What the heck? What is your problem?" I rubbed my arm.

She shrugged. "Well since you kept saying that I punched you when I didn't, I decided to really punch you so then it would be true."

"Gee thanks." I said sarcastically.

"You're welcome." She smirked at me and leaned back.

We sat there quietly for what felt like forever when finally Edwin and Lizzie came out.

"That movie sucked." Edwin announced when they reached us.

"Totally." Lizzie agreed. "I can't believe that we spent $6.00 to see it."

"Are you guys ready to leave?" Casey asked.

"Yeah, can Edwin and Derek stay for dinner?" Lizzie asked.

"Ummm…" Casey started.

"Please?" Lizzie and Edwin begged. I smirked at her.

"Okay fine." Casey agreed reluctantly.

"This is going to be fun." I thought to myself.

Casey's POV

I looked over at Derek and saw him smiling smugly in my direction.

"Okay fine." I agreed.

Great. Why in the heck did I just say yes to that question? Can anybody tell me how someone who gets A's in all of her classes is so dumb?

On the way home I stayed smashed up against the window. No way was I getting any closer to Derek than needed.

When we pulled in the driveway I let myself out and ran inside to tell Mom that they were staying for dinner.

"That's fine. Did you all have a good time?"

"Good is not the word to describe it." I mumbled.

"That's wonderful honey." She smiled and walked into the kitchen.

"I was being sarcastic Mom!" I yelled after her.

Parents. When you want them to say yes they say no, and when you want them to say no they say yes. I love my mom to death but sometimes I think she does this just to see how I'll react.

I went into the kitchen. "What are we having?"

"Spaghetti." She answered.

I made a face. "Eww." I hate Italian food.

Great, so we're having Italian food and Derek is staying for dinner. Could things get any worse?

Derek walked into the kitchen.

Apparently they can. My mom turned around and smiled at him. "And who is this?"

"I'm Derek." He smiled back. " I can see where Casey gets her good looks from. You look like her sister."

"Oh, that's silly." My mom simpered. I can't believe my mom is simpering!

Derek laughed. "No its not."

"Well thank you." My mom beamed at him. "Do you like spaghetti?"

"Yes ma'am I do." He nodded.

Oh brother, does he know how to smooth talk.

About 15 minutes later we were all seated at the table eating. Derek took my spot at the table, the seat on the right hand side of my mom's. Jerk.

It was a boring dinner, with Derek talking sickeningly sweet to my mother and Lizzie and Edwin talking about school friends and computer games. Afterwards Edwin and Derek watched a movie with us.

After about an hour Mom went to bed. Then the irritating Derek came back. Not that he ever left, he was just subtler around my mom.

We were all sitting on the couch, but this time I had managed to secure a seat next to Lizzie at the end of the couch so I wasn't anywhere near Derek.

He was sitting at the other end but he kept looking over at me and grinning.

"What is your problem?" I finally asked.

He shrugged and began watching the movie again. I sighed loudly and looked back at the T.V.

I had seen the movie a dozen times at least so I got up and walked to the kitchen.

I went over to the refrigerator and started to dig around to find a snack.

Someone came up behind me and tapped me on the shoulder. Startled, I jerked up and hit my head on the fridge roof. "Ow!" I rubbed my head and turned around to see Derek leaning against the counter laughing.

"What do you want?" I asked, still rubbing my head.

Derek's POV

I watched Casey leave the room and decided to follow her out. I thought she would hear me right away, but she didn't. When she got to the kitchen, I just stood in the doorway and watched her. She had thrown up her long dark hair into a messy ponytail and was now wearing a pair of fluffy pink slippers. I watched her scuffle over to the refrigerator. She looks incredibly cute right now.

Wait, did I just think that about Casey? I raked my fingers through my hair in frustration and walked up behind her. Leaning over, I tapped her on the shoulder.

She jumped and hit her head on the roof of the fridge. "Ow!" She turned around rubbing her head. I leaned against the counter and started laughing.

Casey's POV "Derek, you are so weird." I crossed my arms and glared at him.

"Not as weird as you Casey." Derek retorted lamely.

"Oh that's really nice Derek. Using the same thing I said to you. Not smart enough to think of your own?" I laughed.

Derek's eyes narrowed and he grinned mischievously. "Remember that warning I gave you earlier today?"

I looked at him and thought back. He couldn't mean… I looked up at his grinning face and knew without asking what he was talking about. Oh no. He is definitely not going to kiss me, no way am I getting my first kiss in the middle of a fight from a boy I can't stand!

I backed up and ran into the fridge. Darn thing, now I have no way to escape. "Stay away from me Derek!" I warned. Panic coursed through me as he stepped closer.

Derek's POV

I stepped closer to Casey. The look on her face was priceless.

Casey's POV

He's getting closer I have to do something! Suddenly I remember the 2-week self-defense course I took last year. Now would be a really good time to put what I learned to good use.

He stepped right in front of me and in 2 seconds flat I had him on the ground wondering how in the world he had gotten there.

"Don't mess with me Venturi." I hissed coldly as I stepped over him and walked out of the kitchen.

Derek's POV

I laid there in a daze for a minute then slowly sat up and rubbed my arm. It was throbbing. She practically wrenched it right off. She actually did a judo move on me to prevent me from kissing her. That's a first. I stood up. Oh wow, apparently it wasn't just my arm that got hurt; my back is killing me too. Geez! I stumbled out of the kitchen.

"Edwin, get up, we're leaving." I ordered as I walked to the front door.

"A little case of hurt pride Derek?" Casey smirked.

"Shut up." She was right, but I was never going to admit it out loud.

I opened the front door and stomped off to my car. Edwin followed a couple of seconds later and jumped into the car. "What's wrong?"

"Her." I pointed to Casey who was now standing at the window waving cheerfully.

"What did she mean about hurt pride?" Edwin asked, clearly still confused.

"Nothing." I replied sharply. I backed out of the driveway and sped down the road away from Casey's house.

"Whatever don't get your panties in a wad." Edwin rolled his eyes and looked out the window.

"I'm going to let that comment slip." I told him.

Edwin just ignored me and turned on the radio, I decided to let him get away with it because I liked the song playing.

Casey's POV

"So what you're telling me is that you already know Derek and you hate his guts. You slapped him across the face in Starbucks, punched him in the arm while you were sitting on a bench, and flipped him onto the kitchen floor, because he tried to kiss you?" Lizzie's eyes widened as she counted the things I had done out on her fingers.

I nodded. It sounded a lot worse when someone said it out loud. "He deserved it." I protested.

Lizzie shook her head. "He certainly brings the worst out in you, doesn't he?"

I nodded and got off the couch. "I'm going to bed." I yawned. "Big test at school tomorrow."

"Good night." Lizzie yawned also.

"Aren't you going to bed?" I asked.

"In a couple of minutes." She replied.

"Okay. Well good night." I trudged upstairs.

I got ready for bed and then sank down into my soft mattress. I smiled sleepily at the memory of flipping Derek onto the floor. That was pretty awesome. I actually couldn't do that in the class. Amazing what you can do when you are panic stricken.

I closed my eyes and almost immediately fell asleep.

Derek's POV

When we got home, I immediately ran upstairs to my bedroom. Getting ready for bed, I started to plot my revenge.

Casey may be beautiful but she is completely insane. I mean who flips a guy onto his back to keep him from kissing her? She needs therapy or something.

I'm going to get her back, I don't know how, or when, but I will.

Nobody humiliates Derek Venturi and gets away with it.
