The Bet

JACE

"You are such a…BASTARD!"

Yeah, like I haven't heard that one before. I stood there, uncaring while my latest—now ex—girlfriend spat profanities at me. Her cheeks were flushed and mascara streaked her face—she looked so much less attractive than I found her a week ago. Sure she was a nice time, pretty enough, decent in bed—but she started to get too clingy. Once girls start looking for emotions it's time to pull the plug.

"Hey look, I don't have time for this." I huffed. I really didn't give a flying fuck what she had to say to me now. I waved off her attempts to call me back and headed towards the exit instead. "Whatever, Stacey." I said dismissively and left her there screaming in the middle of the crowded mall.

I sighed in relief when I gripped the wheel of my car. I couldn't bear to be around any girl I'd just broken up with for more than a few minutes. Maybe once I would've felt bad. There was always a spark of guilt, but that's all it was now. A spark, a flash. There was nothing more, I was numb to the feeling.

I floored it before I could remember what real guilt feels like.

Speeding down the highways home, I felt it again. Not the guilt, no, the superiority. The freedom. Now I can finally leave the summer drama behind me. Well, not really, I still have to see her at school tomorrow. But not even the horrible look on her face I saw just now—or the hate filled death stares I'll get later—could shake the feeling of release that comes with letting a girl go. Now that summer's over, I can start with a clean slate. No drama. No attachments.

Tomorrow's gonna be a bloodbath.

All the girls that spent all summer reworking themselves for the infamous Jace Wayland might actually have a shot, now that Stacey's out of the picture. Hannah looked pretty cute at the end of the year, and I hear that Lauren's not a virgin anymore….

This year is sure to be interesting.

The minute Jace walked in the door, I knew something was up. No, not even something—I knew exactly what was up. It happens every Sunday for fuck's sake….

He sauntered in with his jacket slung over his shoulder, keys jingling lightly on the tips of his fingers. I noticed the sort of bounce to his step and he was even whistling to himself. Whistling? Jace? He was too much of a distraught, girl-dumping, doom cookie for anything that happy! This is getting ridiculous.

"Hey, Izzy!" He called brightly as he passed by.

I sighed, not even pausing to look up from my book. "How did Stacey take it?"

He slowed his pace. "Fine…?"

"Yeah, I doubt that."

"Well, am I supposed to care?"

My eyes flickered to his now. "No, I guess not since it's you." I sneered.

"Oh," He feigned offence. "What's that supposed to mean?"

"You spoil every girl you touch." I accused. "Don't act like you didn't notice." I gathered my things and started up the stairs. Not even bothering to look at him as I breezed by.

"Well I didn't spoil you, did I?" He yelled after me.

"Fuck off, Wayland!" I shrieked and slammed by bedroom door. Asswipe. Everything was calm for a moment, I had enough time to set my book down and plop on my bed before I heard him bounding up the stairs. Seconds later there was a rumble on my door and Jace popped his blond head in. "Love you, Izzy!" I flung a pillow at him. And he deflected it easily. He left but I could still hear his snickers from down the hall.

Ugh. That player! He goes through girls like a nerd goes through books. He treats them like garbage and yet all the girls still fight for him. They get bitchy about it too—don't they know if they wait it out, he'll get to them eventually? No doubt they'll be flocking him when school starts tomorrow now that the news is out. Of course by now it's all over twitter. Stacy's page is full of those typical break-up tweets: "Boys suck. Don't trust Jace Wayland #loveisdead."

So now she finally gets it.

Love screws us over. We all know that, what I don't understand are the girls who go looking for it even after they get burned. Sure, if I find a guy that's cute I'll screw around a little, but nothing too serious. I found it a lot easier to play it safe—no emotions, no relationship. But it's Jace's fault I turned into a heartbreaker—that little fucker. Now I'm just like him, just the less concentrated girl version.

To love is to destroy. And it took an encounter with a certain golden boy for me to figure it out.

My alarm blared on, and instantly the classic sound of Coldplay filled my room. 6AM, it flashed. Damn, school. At least this year was the last—finally Jace and I were seniors—and this one has to be the best. Either that or it would suck terribly. I'm hoping for the first.

I went through my normal routine: shower, clothes, hair, makeup, tumblr, and just as I was packing the last of my things there was a loud banging on my door. "Come on Izzy! I want to go to Starbucks before school!" Jace whined. I shut off everything and grabbed my stuff, opening the door in his face. "Fine, but you're driving. I do not feel like making the drive to Dallas today."

He smirked. "Fine. Just hurry." He bolted down the stairs. I sighed and followed after him, pausing to check my reflection in the large mirror in the living room.

"You look fine, Izzy. Although, I'm not sure school would approve of those shorts." My mother called from the kitchen. She waved her finger in mock disapproval.

I smiled lightly. "Mr. DeLuna won't care. It's an arts school. Fashion is a way of expressing my artistic ability!" I sauntered over to her to accept my awaiting hug, not expecting to get jumped. But of course, that's exactly what happened. Attack of the Overprotective Mom.

"Oh, my baby's a senior! One more year left! What to do?" My mom said between gushy kisses.

"Okay mom, no need to get sentimental….The year just started….Mom!" I squealed while trying to squeeze out of her embrace.

"Hey, Mayrse! Can you let your daughter go so we can leave?"

Instantly she stopped and all eyes flew to Jace, who was impatiently waiting by the stairs. I could tell he felt uncomfortable watching Mayrse show affection towards me like this. Mayrse must've noticed it too because she promptly flew over to Jace and showered him with kisses also.

"Oh, Jace! You're practically my son! You are so talented, my senior!"

Jace made a gagging noise. "Did Alec get this much attention when he was a senior? I don't remember this many—" Jace paused to wiggle out of Mayrse's death grip and succeeded, but not before she planted another kiss on his forehead. "This many kisses…."

I grabbed Jace's hand and dragged him to the door before this lovefest could start again. "Bye mom!"

Her face dropped. "Where are you going so early?"

"First day Starbucks!" Jace called over his shoulder.

"But I made breakfast!" She whined.

"Give it to Max!" We both yelled in unison. We passed by his door on the way out and shouted a chorus of "Bye buddy! Have fun at school! Yay 5th grade! See ya later!" And bolted out the door before Mayrse could say another word.

I sat down at one of the little café tables and rolled my eyes at the obvious sight. "Who could you possibly be texting at 8 in the morning?"

Jace's eyes flicked up. "It's 8:15," He said sassily. "And Jackie. She got really cute over the summer and—"

"You disgust me." I shook my head slowly. "Didn't you just break up with Stacey?"

"Yeah, so?" He shrugged.

"Haven't they been best friends since like, 3rd grade?"

"Your point?"

"I'm trying to help you here!" I nearly squealed.

"Well, help me help myself! Talk to Jackie for me! You know her right?"

I glared at him over my tea. "I'm not going to help you ruin some girl's senior year!"

"Who says I'll ruin it?" He smirked and casually leaned back in his chair. "Hell, I'll probably make it her best year yet!"

I scowled at him. "Why do I talk to you again?"

"Because we live in the same house."

"Sometimes I wish we didn't." I muttered too low for him to hear. Not that mattered. He was tapping away at his phone again. "I bet you couldn't even stay with a girl for a year."

"Of course I could Izzy! I just never have the motivation."

Instantly an idea floated into my head. "But what if you did have the motivation?"

He paused mid sip and gave me a guarded look. "What are you getting at Izzy?"

I sat for a minute, thoughtfully sipping on my drink. What could be better than proving him wrong? I laughed inwardly. Playing with his weaknesses and watching him lose!

I had to admit; sometimes I can go too far when it comes to toying with Jace. But this time it was slightly different. This might actually help him….I might be able to get him to care. Suddenly my idea went from something masochistic to something beneficial. Maybe I could bring the old Jace back. There was a dull aching in my heart, and then a fire. I had to do this! It's for the good of the female population!

It wasn't hard to find his weakness. All I had to do was list of all of Jace's faults when it comes to his relationships. He can barely stay with a girl for more than a week, and he only wants them in bed. He never really gets to know them nor does he even like them for their personality…what to do? I wanted to make this as hard as possible—at least if he doesn't learn anything I would have the pleasure of watching him squirm. I smiled at the thought. It was perfect! Surely this would make this year exciting for the both of us. Everything seemed to be working itself out in my head—all I had to do was give him a prize and he would be won.

"Make a bet with me, Jace?"

His confusion turned to shock, and then interest. "It depends…" He mused. "What are the guidelines and what happens if I win?"

Oh it's on now.

"I bet that you couldn't stay with a girl for longer than a school year. So to prove me wrong, you must do so…with the girl of my choice."

His face dropped immediately. He opened his mouth to protest but I cut him off.

"You scared, Wayland?"

His mouth popped closed.

"Don't worry, I won't be too mean! Clary Fray isn't a bad girl after all!"

"Clary Fray?!" He nearly screamed. "The red head in visual? Are you crazy?!"

"No I'm not. I'm doing you a favor!"

He stared at me, eyes wide. "Oh really? How?"

"Because I know you like her. You told me yourself."

"I did no such thing." He said quickly.

"Actually you did." I countered. "Don't try to deny it."

He got quiet for a moment, either trying to remember or regretting the truth. He threw his hands in his face and groaned at the table. "It was freshman year, Izzy! This will kill my reputation!"

"Oh, I'm sorry this little bet will hurt your ego!" I said sarcastically. "And you know those crushes never really go away, right?"

I waited, feeling superior when he slowly dropped his hands. "Fine, I'll do it. What else then?"

"Well first you have to get her to like you and—"

"That won't be an issue." His arrogance was back on, as usual. "Every girl likes me!"

You'd be surprised about Clary. I thought. She's stronger than you think.

"So, you have to get her to like you—in fact, you two will have to be together by Christmas break. And then you have to stay with her until after graduation—get to know her, learn to love her. And try not to sleep with her. Or cheat on her—that's an automatic forfeit. Oh! And I want a paper! Tell me all about her and why you like her! Due the last day of school!"

Okay, maybe this is a little much. Oh, wait. Do I care?

Nope.

His expression had changed somewhere during my speech. Now his face was a mix of boredom and irritation. "Remind me again why I'm doing this?"

"Because you're Jace Wayland! You never back down from a challenge!" I teased. "And also, if you win I'll…" I struggled to say the words. "I'll be your bitch for the day!" I cursed myself. The last thing I wanted was to give into Jace's demands for a whole day—but I did want to see him fight for Clary's affection…and who said he could win anyways?

He seemed to be pondering my offer also. The light had returned to his eyes and there was a devilish smirk creeping onto his face. "My bitch, you say?"

I pursed my lips and nodded. "Anything you want for a whole day."

The devilish smirk had turned into a full-fledged evil grin that turned my body stone cold. I didn't even want to think about what terrible things he was thinking of making me do. Jace has a very vivid imagination, mix that with the possibilities in reality and he'll go wild.

I'm starting to regret this….

"I'm sold!" He chortled and extended his hand. "You've got yourself a deal!"

"Not so fast! You didn't even hear what I had to say if you lose!"

His golden eyes flashed up to mine as he shot me a charming grin. I grin that I'm sure has won the hearts of many girls. But not mine. Not anymore at least. "Do you really think I'll lose, Isabelle? Get ready to lose that inky black hair of yours!"

I rolled my eyes and shook his hand, sealing the deal. "I guess I'll have to wait and see."

Wait. What did he just say about my hair?!

Shit. What did I just get myself into?
